## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation of U.S. patent application Ser. No. 12/831,946 filed on Jul. 7, 2010, which claims priority to U.S. Provisional Patent Application No. 61/223,978, filed Jul. 8, 2009, and entitled “Incorporating Macroeconomic Forecast Information Within Geodemographic Household Classification Systems,” both of which are hereby incorporated by reference as if set forth herein in its entirety.


BACKGROUND
The invention relates to the field of econometric analysis. Specifically, it relates to forecasting household economics based on macroeconomic data.
Predictions of household economics have a wide range of uses. Such predictions can indicate the likely sources of income for households and income amounts, likely expenditures and products and services purchased, amounts saved per household, and other similar information. This data can be used by advertisers seeking to target advertisements to households of interest, by government policy makers seeking to determine the effect of legislative and regulatory changes, by investors seeking to determine the risk of an investment, and so on.
Techniques for predicting macroeconomic changes, such as GDP, employment rates, interest rates, and the like, are well-known in the economic literature. However, these macroeconomic variables provide only a high-level analysis, without differentiating among different types of households. These macroeconomic models, then, are not able to provide the fine-grained analysis that may be required for decision-making in many circumstances.
SUMMARY
Various aspects of the invention are directed to systems and methods for forecasting household economics. One aspect of the invention is a method of forecasting household economic data based on a macroeconomic scenario. In this aspect, a storage media of a computer maintains household survey records, and geodemographic segment identifiers are added to those records. A computer processor is used to aggregate the household survey records by geodemographic segments. The resulting segment-level records can be applied to an econometric model, and the model can use macroeconomic forecast assumptions related to the macroeconomic scenario, thus producing economic forecasts for the geodemographic segments. The economic forecasts that are produced may include predicted income and expenditures for each of the geodemographic segments.

In one embodiment of the invention, the steps depicted in FIG. 1 are performed. Household survey data are collected at step 101. Survey data may include a variety of information collected about households by any means, including statistical sampling, census data, mailed surveys, data collected by private organizations such as banks or merchants, and so on. In an embodiment, the household survey data includes at least three broad categories: gross household income, deductions from gross household income, and household expenditures. Gross household income may include wages and salaries, self-employment income, investment income, annuities and pensions, social security or other governmental benefits, and other sources of income. Deductions from gross household income may include income taxes, social security taxes, and other taxes, as well as costs such as mortgage or loan payments. Deductions from gross household income may alternatively be characterized as household expenditures. Household expenditures include amounts spent by households out of disposable income. In one embodiment, expenditure categories are based on the Classification of Individual Consumption According to Purpose (COICOP), published by the United Nations Statistics Division, which is hereby incorporated by reference. It is contemplated that other categories of data may be included, or some categories of data will not be included, in the household survey data. Additionally, in some embodiments, the data is separated by individual categories, so as to allow for particularized analysis in further steps. In one embodiment, each record in the household survey data may represent a single household, or a group of households. Other data structures or representations of household survey data may be alternatively used.
At step 102, geodemographic segmentation data is collected. Geodemographic segmentation data provides information about “segments,” or groups of geographical areas that tend to have certain similarities, on the basis that people who live in the same neighborhood are likely to share a number of characteristics and behaviors. The geodemographic segmentation data may indicate characteristics of geographical areas, such as by ZIP code, voting district, state, city, county, or other units. The data may incorporate information on the financial resources and spending behavior of household segments. The data may include quantitative estimates of the economic resources available to household segments from income and accumulated wealth, as well as the spending patterns of those household segments. Such estimates may be based on historical information, survey data, statistical sampling, census data, privately collected data, or other data sources. In one embodiment, Experian's MOSAICTM and PIXELTM data are included in the geodemographic segmentation data.
At step 103, a data mapping and aggregation function is applied to the household survey data and the geodemographic segmentation data. The mapping function may associate the data sets based on a common join variable, such as ZIP codes or other address codes. A join variable, as understood by those of skill in the art, is a data field present in multiple data sets that may be used to identify and join matching records in the data set to create an augmented data set. So, for example, a record in the household survey data having a particular ZIP code may be matched with a record in the geographic segmentation data having the same ZIP code. Those of skill in the art will be familiar with other methods of identifying matching records among multiple data sets, such as fuzzy matching, lookup tables, statistical correlation techniques, and so forth. Detailed implementations of embodiments of the data mapping and aggregation function are described throughout this specification, such as with regard to FIGS. 2-4.
The data mapping and aggregation function produces a data set of segment-level household accounts, indicated in step 104. This data set may incorporate parts or all of the household survey data and parts or all of the geodemographic segmentation data.
At step 105, a set of macroeconomic forecast assumptions is gathered, and the forecast assumptions and segment-level accounts are provided as inputs to one or more econometric models in step 106. The macroeconomic forecast assumptions include data representing macroeconomic variables relating to a certain macroeconomic scenario. This may include, for example, gross domestic product, employment rates, unemployment rates, household income statistics, income growth rates, interest rates, consumer product indexes, inflation indexes, product prices, asset prices, total household expenditures, or other values. When the econometric models are applied in step 106, they produce household segment forecasts at step 107. These forecasts may include forecasts of household incomes and expenditures, and they may include particular forecasts of particular income sources and expenditure types. The process of applying macroeconomic models is explained in further detail throughout this specification, such as with regard to FIGS. 5-6.
The econometric models may be generated at step 106 or elsewhere based on historical data from the household accounts or other data. In an embodiment, a statistical analysis is conducted of historical relationships between macroeconomic variables, such as the ones above, and household finances within the geodemographic segments. This analysis may be done, for example, using time-series analysis or panel estimation techniques, or with other well-known statistical methods. The resulting relationships are then used to predict future household financial circumstances and spending behavior for the geodemographic segments. The historical information on household financial resources and expenditure patterns may be compiled based on a household classification scheme defined by income, location, household structure, or other means, rather than a geodemographic segmentation scheme. In this case, the statistical analysis produces relationships between household financial circumstances and spending behavior for household types within this alternative classification, and these relationships are then mapped to geodemographic segments based on characteristics of the geodemographic segments and the alternative household classification.
FIG. 2 illustrates a data mapping and aggregation function of one embodiment of the invention. In this embodiment, household survey data 201 (such as that of 101) includes an address code field, such as a ZIP code, and a date range field, among other data fields. The date range field, in this embodiment, indicates a time or time period to which the survey record is relevant. For example, the date range field may indicate the date when the survey was taken, a range of dates between which data was collected, etc.
A geodemographic segmentation address lookup 202 includes a mapping between address codes and household segment identifiers. Thus, the geodemographic segmentation address lookup can be used to determine the pertinent geodemographic segment for a given address code.
Ordinarily, the household survey data 201 and geodemographic segmentation address lookup 202 are sufficiently large to produce statistically significant results when the analyses described here are performed, so the data sets are joined, using a computer processor, based on the respective address code fields of the data sets, so that the household survey data 201 is augmented with a household segment field to produce an augmented data set 203.
Next, the data records are aggregated by household segment and date range, to produce a data set 204 with individual records for each unique household segment and date range. The aggregation of data fields may be done by calculating the mean, median, mode, sum, or other aggregate value of each data field, for all data records having the same date range and household segment. For example, to aggregate the “Wages and Salaries” field, the wages and salaries of each household in a given segment for a given date range may be averaged, to produce an average wages and salaries Numerous aggregation functions are well known in the art. In one embodiment, the aggregation is performed in part by performing, in a relational database, a specialized SELECT statement in the SQL language, including a JOIN and a GROUP BY clause. Other methods of performing the above steps will be well known to those of ordinary skill in the art.
Another embodiment of a data mapping and aggregation function is provided in FIG. 3. In this embodiment, a first household survey data set 301 may lack an address code field. A second data set 302 includes socio-demographic and location characteristics of various households or groups of households, and includes a household segment field. The second data set is aggregated by household segment to produce average characteristics of household segments 303. Alternatively, the second data set 302 may be data already aggregated by household segments, so the aggregation step is not necessary. Next, the characteristics of the household survey data 301 are compared to the aggregated values of step 303, so that each household record may be augmented with a household segment to produce data set 304. The records of the new data set 304 are aggregated, as above, by household segment and date range, to produce a data set 305 with individual records for each unique household segment and date range.
Another embodiment of a data mapping and aggregation function is provided in FIG. 4. In this embodiment, household survey data 401 is already aggregated by some sociodemographic, location, or other characteristics into groups. This may be the case, for example, when micro-level data, or survey data individual to single households, is not available, or the data provider has previously aggregated the data. Average characteristics of household segments 402 include average or otherwise aggregated socio-demographic, location, or other characteristics for individual household segments. By matching the characteristics of the groups of the household survey data 401 with the average characteristics 402, it is possible to produce a data set with individual records for each unique household segment and date range 403. For example, if a particular household segment S is characterized by having certain values for a variable X, then it can be inferred that this household segment is similar to household survey data records R having similar values for the same variable X. Thus, one way to determine the value of a second variable Y for the household segment S would be to estimate it based on the corresponding Y values for the matching household survey data records R. This estimation may be done with standard statistical techniques, such as linear regression, neural networks, automated simulations, or the like.
FIG. 5 depicts a process for applying macroeconomic forecast assumptions to segment-level account data to produce segment-level income and expenditure forecasts, as used in one embodiment of the invention. Macroeconomic forecast assumptions 501, as described previously, are provided as inputs to macroeconomic models 502. Macroeconomic models 502 convert macroeconomic forecast assumptions 501 into forecasts for key macroeconomic variables via a set of equations describing relationships between variables, typically estimated on the basis of historical data. Many such models are well known, and they typically generate forecasts for aggregate variables related to total output and income, employment and unemployment, household incomes, financial variables such as interest rates, prices, and other variables described throughout this specification or otherwise well known.
Additionally, the forecast assumptions 501 and/or outputs of the macroeconomic models can be applied to macroeconomic satellite models 503. These satellite models provide additional detail related to household finances and can be used to create more detailed macroeconomic forecasts to drive segment level forecasts. Values modeled by the satellite models 503 may include output, employment and/or unemployment for individual industries, regions, occupations, socio-demographic groups, locations, etc. They may also model household income by income source type, interest rates by type of debt, detailed price deflators for individual products, prices by types of assets, household expenditures by product types, household assets and debts, and so on.
In an embodiment, the output of the macroeconomic models 502 and satellite models 503 is a set of macroeconomic drivers of income and expenditures 504. These macroeconomic drivers may include general macroeconomic values and detailed values related to household finances, such as employment, household income by source, assets and debts, interest rates, inflation, expenditure by type, and so on. The macroeconomic drivers are provided as inputs to segment-level income and expenditure models 505, along with the segment-level account data 506 calculated as described elsewhere in this specification, such as with regard to step 104 of FIG. 1. The segment-level models, then, are applied to produce income and expenditure forecasts 507 for individual geodemographic segments.

Table 1 shows a sample use of a forecast calculated by an embodiment of the invention. In the “Segment” column, each geodemographic household segment is listed. The three columns “Disposable Incomes,” “Total Spending,” and “Spending on Food” indicate the percentage difference between actual macroeconomic data, where interest rates increased in the later part of 2006, and forecasted macroeconomic data, with the macroeconomic assumption that interest rates did not increase in the later part of 2006. As this table shows, an individual forecast is calculated for each of the geodemographic household segments.
An embodiment of a process for using macroeconomic drivers and segment-level models to produce segment-level forecasts is shown in FIG. 6. This process may be used, for example, at steps 504 through 507 of FIG. 5. Macroeconomic income drivers 601 and macroeconomic expenditure drivers 602 are received, for example, from calculations such as those described elsewhere in this specification, such as with regard to FIG. 5. Two types of segment-level models are used in one embodiment: income models 603 and expenditure models 604. In other embodiments, additional or different models may be applied. The segment-level models may include mathematical equations and identities that may be parameterized in a variety of ways, including the user of time series models, panel econometric estimation techniques, linear regression, nonlinear regression, recursive partitioning, neural networks, or other techniques of multivariate analysis.
The methods of creation and application of the various econometric models are standard statistical and mathematical techniques known to those of ordinary skill in the art. The particular method will depend on the nature of the model created. For example, in an embodiment, the econometric models may include linear regression coefficients. In this embodiment, the segment-level accounts are used as sample data to calculate the linear regression coefficients, thus creating the models. The macroeconomic forecast assumptions may include numerical values that serve as independent variables to the linear regression, and the predicted values of the dependent variables serve as the forecasts of household incomes and expenditures. In other embodiments employing different statistical models, the appropriate well-known techniques for generating and applying the models are used.
In an embodiment, the income models 603 include models for household income by income source. Income sources may include wages and salaries, profits from investments, property incomes, financial transfers, annuities and pensions, and other income sources, such as those listed for step 101 of FIG. 1. The income models may model income for each source individually, or they may aggregate some or all of the sources. The expenditure models 604 may include models for total expenditure and savings for a household, expenditures by individual products or product types, or other similar models. Product types may be separated into categories using the COICOP classifications described previously, or by other systems.
At step 605, the income models 603 are used to forecast the gross income for a household by income source, for the geodemographic household segments, by applying the appropriate mathematical equations and identities described above. The gross income values are then used as inputs to one or more income redistribution models 606. These models may account for income taxation and other forms of taxation, as well as other fixed costs such as mortgages, loans, and other costs. Applying the income redistribution models produces forecasted net income by geodemographic household segment 607. The forecasted gross income and net income may be aggregated and/or separated by income types.
At step 608, the expenditure models are used to forecast household savings and expenditures. These forecasts may be grouped by geodemographic household segments, expenditure types, savings types, and combinations of any of these. Combining the forecasted savings and expenditures 608 with the forecasted net income 607 produces a segment-level forecast 609 that may include information about total spending, saving, spending by product, total income, income by source, and other such information.
In another embodiment, segment-level forecasts, as shown in steps 504 through 507 of FIG. 5, may be determined using a process shown in FIG. 7. Household survey data 701 and geodemographic segmentation data 702, such as that described with reference to FIG. 1, are initially collected. In step 703, a data mapping and aggregation function is applied to produce micro data 704, which is household-level data augmented with geodemographic segments but not aggregated by the segments. Macroeconomic forecast assumptions 705, also described with reference to FIG. 1, are used with the micro data as inputs to one or more microeconometric or simulation models at the household level 706. These models are used to predict income, expenditure or other variables for individual households driven by macroeconomic forecast assumptions 705. The models may be generated using methods and historical data as described with regard to FIG. 1. Application of the models produces forecasts for individual households 707. The household-level forecasts can then be aggregated by geodemographic segments in step 708 to produce forecasts aggregated by geodemographic household segments.
In one embodiment, the economic forecasts by geodemographic household segments are used to provide further information about populations, samples, and subgroups, as shown in FIG. 8. In this embodiment, the output of interest is not forecasts for each of the household segments, but rather forecasts for various subgroups of people that do not necessarily correspond to the household segments. Subgroups may be geographically defined (e.g., cities, school district zones, water districts, etc.) or they may be defined by other characteristics (e.g. family size, household type, education status, etc.). Thus, the outputs of processes described with regard to FIGS. 1 and 7, among others, may be used as inputs in the following embodiment, to make predictions about the subgroups.
A household data file 801 with records for individual addresses mapped to subgroups is used as an input. Using a geodemographic address lookup table 802, the household data file can be augmented with geodemographic household segments, by methods such as those described with reference to FIGS. 2-4, for example. Further augmenting the household data file with economic forecasts for each geodemographic household segment produces a household file 803 with economic forecast data (shown in the last six columns of 803). This data can now be aggregated by the subgroups to produce subgroup-level economic forecast data 804. Depending on the nature of the subgroups, the resulting aggregated data file may have many uses, including, for example, generating estimates and forecasts for customer groups, analyzing alternative household segmentations, determining effects of macroeconomic policies on particular groups of interest, and so on.
An alternate method of determining economic forecasts for different subgroups is shown in FIG. 9. A household profile 901 is received, indicating a number of subgroups of households. The profile is combined with a geodemographic profile 902 that includes information about the fraction of each subgroup corresponding to each of the geodemographic segments. After calculating the economic forecasts for each geodemographic segment, it is possible to obtain economic forecasts for each of the household subgroups 901 by, for example, calculating a weighted average of the economic forecast values with the weights being the fractions included in the geodemographic profile 902. Thus, by this method, it is possible as well to produce economic forecasts for each subgroup. It is also possible to calculate an economic forecast for a particular group of households, using methods similar to the ones described above.
FIG. 10 shows a computer system used in an embodiment of the invention. Computing device 1001 may include, among other things, a mass storage device 1002, multimedia devices 1003, a central processing unit made up of one or more processors 1005, various input/output interfaces and devices 1006, volatile and/or nonvolatile memory 1007, and various data sources 1008. Various embodiments of the invention may include a subset of these components as necessary to implement the methods described above. Furthermore, the computing device 1001 may be connected via a network 1011 to other computing devices 1009 or 1010, and/or to external data sources 1012.
Instructions for performing those methods are stored in macroeconomic forecasting modules 1004, which may be encoded in a digital form on a computer-readable medium and stored in one or more storage components of the computing device 1001, such as the mass storage device 1002, the multimedia devices 1003, the input/output devices 1006, the memory 1007, the data source 1008, at locations accessible via the network 1011, or other places. In one embodiment, executable modules are loaded into a volatile memory 1007 in order to ensure fast processing of the module instructions. The modules may be executable on the central processing unit 1005 to automatically perform the desired procedures.
Data inputs used in the described methods may be stored in the various storage components of the computing device 1001 or at locations accessible via the network 1011. For example, the historical household survey data 101 or geodemographic segmentation data 102 of FIG. 1 may be stored in external data sources 1012, which may be the case if those data sets are offered by external vendors. Alternately, they may be stored locally on the computer, which may allow for faster access to the data.
When the described methods for generating household segment forecasts are performed on the processor 1005, the data may be used for various purposes according to embodiments of the invention. For example, the forecasts may be used to produce reports for a user, via the multimedia devices 1003 or the input/output devices 1006. Alternately, the forecasts may be used for further data analysis, such as those described with respect to FIGS. 8-9. The forecasts may also be used, with or without further analysis, to generate alerts. In one embodiment, the forecasting methods are executed in real time and/or on a periodic basis and used to generate alerts if the values reach a certain threshold. This may be used, for example, for regular monitoring of macroeconomic status.
In another embodiment, parts or all of the described methods are performed at the request of a user transmitted from an external user computing device 1009 or 1010 via the network 1011. In this embodiment, the computing device 1001 acts as a server, receiving client requests. For example, with regard to the method described in FIG. 1, the steps of data mapping and aggregation 103 to produce segment-level accounts 104 and/or the steps of generating the econometric models 106 may be precalculated with the results stored in the computing device 1001. The macroeconomic forecast assumptions 105 may be transmitted from a remote user computing device 1009, and then the computing device 1001 applies the econometric models to produce household segment forecasts 107, which are encoded and transmitted over the network 1011 back to the same user computing device 1009 or another user computing device (e.g. 1010). In another embodiment, all of the steps shown in FIG. 1 are performed when the user request is received. The user may provide all of the input data required to perform the requested methods, or some of the input data, or none of the input data, and the computing device 1001 may be configured to use internally stored data or externally located data to supplement data received from the user. It should be clear to those of ordinary skill in the art that any of the methods described in this specification may be performed, in whole or in part, in this manner.
Although the above description has focused on households as the units of analysis, it is contemplated that the invention is not necessarily so limited. Systems and methods analogous to those described could be applied to individual persons, businesses, local neighborhoods, occupants of residences or other structures, geographical areas, or other such divisions. Additionally, the analysis units, such as households, may be grouped together or clustered, so that the groups or clusters are analyzed, without departing from the spirit of the invention.
All references cited herein are intended to be incorporated by reference. Although the present invention has been described in terms of specific embodiments, it is anticipated that modifications and alterations to the invention will be apparent to those of ordinary skill in the art. It is thus intended that the above disclosure be construed as illustrative of embodiments of the invention and not restrictive of the invention, and that the scope of the invention be determined by the claims.
