- Average Household Size: 1970-2000

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**

Average household size has been dropping steadily over the century and now stands at 2.59 persons per household, down from 3.14, just three decades ago.

Average household size is also closely related to household type. As you’ll see, the composition of American households has also been changing.

## Households by Type and Size: 1990-2000

**1990**

**2000**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
The vast majority of family households--that is, households containing at least one person related to the householder by birth, marriage or adoption--were married couple households: about 54.5 million households or about 52 percent of all households.  Family households maintained by women with no husband present numbered almost 13 million, almost three times the number of households maintained by men with no wife present.  Among non-family households, one person households predominated.

Utah had the highest number of persons per family (3.57), closely followed by California (3.45).

Washington, DC had the highest percentage of single person households: 44, with North Dakota a distant second at 29 percent.

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
We have a full line of products: the very detailed sets of data tables contained in summary files, demographic profiles if you need just an overview of an area, quick tables for looking at several key items for a single area, geographic comparison tables if you want to compare across geographic areas, printed reports, and maps and related geographic products, and microdata.
The information will be available in a variety of media, including Internet, disc, and print, including print-on-demand and publications.

And, depending on the specific product, it will likely be available in several different electronic formats.

## Media

**Internet**
**CD-ROM/DVD**
**Paper**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Let’s look first at the different media:

We will release most Census 2000 information first via the internet and the American Factfinder.  The same information will also be released, generally a few weeks later in the process, on CD-ROM.  Once all states in a series are released, we will issue the product on DVD.

There will also be a variety of products available on paper, including printed publications, and maps. We will also have print-on demand capabilities available for users who need an official printed copy.

## Internet

**Data released first on American FactFinder**
**Community profiles available under QuickFacts **
**Printed reports available in Portable Document Format (PDF)**
**Maps available in Portable Document Format (PDF)**
**Download (FTP) options**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Data will be released first on the Internet through an access tool called the American FactFinder. 

For users who don’t need the detailed data, key variables and demographic profiles will be available directly from our homepage.

While many key tables will be available in printed reports, we will also make these printed reports available in portable document format on the internet and on CD-ROM. Maps as well will be accessible in PDF on CD-ROM and on the Internet.

While users will be able to download files directly from our Internet site, we suggest that industrial strength users consider CD-ROM and DVD as an alternative. Given the size of some of our files, and modem speeds, the downloading process could take several days for some users. 

## Slide 13

**Notes:**
Here’s the Census Bureau’s homepage.  There are several ways of getting to the Census 2000 information.  You can click on Census 2000 for background information and for links to various products.

Click on State and County QuickFacts if you need a quick overview. The QuickFacts include key data items from a variety of Census Bureau programs and surveys.

To get to American FactFinder you can click on the banner; you can click on American FactFinder in the dark blue left-hand column; or you can click on A in Subjects A-Z; or follow the various links to American Factfinder  throughout the site.

You will be taken to the American FactFinder homepage...

## Slide 14

**Notes:**
...which looks like this. 

Start with Basic Facts, choose the geography and the data items you want to see.
Or, you can click on the Geographic Comparison Tables or Quick Tables for additional information.  

Choose Data Sets if you want to download entire state files, rather than selected tables for specific geographic areas.

## CD-ROM / DVD

**Redistricting Summary File and 4 series of detailed tables similar to 1990 STFs**
**Profiles, Quick Tables, Geographic Comparison Tables, and printed reports (PDF)**
**Maps (PDF)**
**Access software**
**Formats**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
In addition to the Internet, you can also get Census 2000 information on disc.

We plan to release various files on CD-ROM, just as we did in 1990.  These will be released on a state-by-state basis; once all the states in a particular series are released, we will repackage the entire series on one or more DVDs.

The complete set of block maps and tract outline maps will also be available on disc.

Rather than developing our own software as we did in 1990, we are looking at off-the-shelf software to accompany the summary files on CD-ROM and DVD. Initial review of the software and its capabilities by state data centers, depository libraries and other data users have been surprisingly positive.

We will also make the files available in ASCII format.

## Paper

**Printed reports **
**Maps **
**Print on demand**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Even though there will be much information available in electronic media, we will also produce quite a few paper products as well. 

These include 3 series of printed reports with pages of data tables, as well as a series of short informational briefs with some analyses, tables and charts.

As we did in 1990, we will produce printed maps on demand. There will also be several thematic or data maps that will be printed through the Government Printing Office, including a Census 2000 version of the “Nighttime map.”

We are also offering print on demand for those users who may need a printed version of a product that is only available in electronic format.

## Paper

**3 Series of printed reports **
**Summary Population and Housing Characteristics**
**Summary Social, Economic and Housing Characteristics**
**Population and Housing Unit Totals**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Each of the printed report series will contain a separate report for each state with information for the various governmental entities in that state.  Each series will also have a national summary volume for people who want to compare across states. 
The first series will contain tabulations of 100-percent data, comparable to CPH-1 series of 1990.
The second series will contain sample data for each of the governmental units in the state,  comparable to the 1990 CPH-5 series.
The third series will present population and housing unit counts for governmental units for 1980, 1990 and 2000, comparable to CPH 2.

## Paper

**Census Briefs**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**

The Census Briefs present a short analysis,  generally at the national level, of most of the specific topics that were asked in the census, such as gender, housing, household relationship, and population distribution, and will include briefs for specific race groups.

## The Census Questionnaire

**	****100% data or short form:**
**7 questions**
**	****Sample data or long form:**
**34 topics**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
The Census Bureau used two different forms to collect Census 2000 data. A short form (100% data) with seven basic questions went to all households, and a long form with these same questions and additional questions went to a sample of households. Summary File 1 presents counts and basic cross-tabulations of information collected from all people and housing units.
The questions asked on the short form included: name; sex; age; household relationship; Hispanic origin; race, and whether the home was owned or rented. About 83 percent of households received the short form. The information that is tabulated from the questions asked of every person and housing unit is called the100-percent or short-form data. 
The long-form questionnaire included the same seven population and housing questions plus additional inquiries. On average,1 in every 6 households received the long form. The information that is tabulated from the questions asked of this sample of persons and housing units is called sample or long-form data. 

## What Data Will Be Available?

**100% data or short-form information**
**Redistricting Summary File**
**Summary File 1**
**Summary File 2**
**Sample data or long-form information**** **
**Summary File 3**
**Summary File 4**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Census 2000 information is released on a flow basis in a series of summary files, basically a set of predefined tables for various levels of geography. 

Information from the short-form questions (100% data) is released first. Short-form information is included in the Redistricting Summary File, and Summary Files 1 and 2.

Summary File 3 information from the long-form (100% data plus additional questions on income, education, occupation, housing rent and value) is tabulated later in the process and will be available starting in the Summer of 2002.

Summary File 4 presents data similar to the information included in Summary File 3. These data are shown down to the census tract level for 366 race, Hispanic or Latino, and American Indian and Alaska Native categories, and ancestry groups that meet a specified minimum population size requirement. 

## Redistricting Summary File

**Total population and 18-and-over population by 63 race categories and Hispanic/Latino**
**Lowest level of geography: block**
**1 or more CDs per state; 3 DVDs**
**Race and Hispanic or Latino Summary File (National File)**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Let’s turn our attention to some specific products:

One of the first products released was the Redistricting Summary File, used by states to redraw legislative district boundaries. The Redistricting File contains very detailed race data down to the city block.  

You may remember that, as a result of new Federal guidelines for how data on race should be collected and tabulated, people could check as many of the racial categories as were necessary to identify themselves on the census questionnaire. As a result, some of the race tabulations are very detailed.   This file contains tables down to the block level showing the total population and the population18-and-over for 63 race categories and for the Hispanic or Latino population. 

The file is available on the Internet and on CD-ROM.

## 100 Percent Summary Files

**Summary File 1 (SF1)**
**Counts and cross tabulations **
**Counts for detailed race, Hispanic or Latino groups, and American Indian/Alaska Native tribes**
**About 300 tables**
**Tables repeat (A-I) for major race groups alone, two or more races, Hispanic or Latino, White not Hispanic or Latino**
**Geography: block, census tract**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
We will also produce a series of 4 summary files, 2 with 100-percent data and 2 with sample data. 

In 1980 and 1990 these were called summary TAPE file, but we’ve since dropped “tape” from the name. You may be aware that we stopped releasing information on computer tape 2 years ago.

Summary File 1 will provide various counts and some cross-tabulations of the data that was collected from every person and housing unit in about 285 tables. Information will be available down to the block level as well as for other geographic levels, including Zip Code Tabulation Areas and Congressional districts.

Median age, household size, tenure by age of householder, group quarters population, etc., are some of the data items that will be available on this file.

Some tables will only be available at the tract level.

## SF1 Subject Content 

**171  Population tables (P) at the block level**
**  ****56  Housing tables (H) at the block level**
**  ****59  Population tables (PCT) at the census ****	****       ****	****	****tract level**

-  **286  Tables**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Summary File 1 (SF 1) contains the 100-percent data, which is the information compiled from the questions asked of all people and about every housing unit. Population items include sex, age, race, Hispanic or Latino, household relationship, and group quarters. Housing items include occupancy status, vacancy status, and tenure (owner occupied or renter occupied).
There is a total of 171 population tables (identified with a “P”) and 56 housing tables (identified with an “H”) shown down to the block level, and 59 population tables shown down to the census tract level (identified with a “PCT”) for a total of 286 tables. There are 14 population tables and 4 housing tables shown down to the block level, and 4 population tables shown down to the census tract level that are repeated by the 6 major race categories (White; Black or African American; American Indian or Alaska Native; Asian; Native Hawaiian or Other Pacific Islander; and Some Other Race), and Hispanic or Latino.
SF 1 includes population and housing characteristics for the total population, population totals for an extensive list of race (American Indian and Alaska Native categories, Asian, and Native Hawaiian and Other Pacific Islander) and Hispanic or Latino groups, and population and housing characteristics for a limited list of race and Hispanic or Latino groups.

## SF1 Releases

**Individual files**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Summary File 1 (SF 1) is released as individual files on a flow basis for each of the 50 states, the District of Columbia, and Puerto Rico; and then for the United States as a whole, and includes summaries for states, metropolitan areas and other higher levels of geography in a single file. The tables (matrices) are identical for all files, but the geographic coverage differs.

**Notes:**
State Files: SF 1 for states, the District of Columbia, and Puerto Rico provides data for these areas and their subareas in hierarchical sequence down to the block level (census tract level for some matrices - PCT tables). The file structure includes, but is not limited to, the geographic entities shown on the slide: state, county, county subdivision, place (or place part), census tract, block group and block.

SF 1 for states also has inventory (complete) summaries for the following geographic areas; place, census tract, block group, congressional district (106th Congress), consolidated city, metropolitan area and ZIP Code Tabulation Area (ZCTA).

DEFINITIONS:
Hawaiian Home Lands -  Areas created as a result of the Hawaiian Homes Commission Act of 1920 to provide agricultural, pastoral, and residential land for native Hawaiians. New for Census 2000.
American Indian Trust Land - Land held in trust by the federal government for either a tribe (tribal trust land) or an individual member of a tribe (individual trust land). Such land always is associated with a specific federally recognized reservation or tribe but may be located on or off the reservation. The Census Bureau recognizes and  tabulate data separately only for off-reservation trust  lands. See American Indian Reservation and Hawaiian Homelands.

NOTE: The Office of Management and Budget (OMB) announced revised standards for metropolitan statistical areas, and a new type of entity called a micropolitan statistical area, in the Federal Register on December 27, 2000. However, the OMB will not identify the entities that are based on the new standards and Census 2000 data until mid-2003. The Census 2000 data products present information for the metropolitan areas and central cities announced by the OMB on June 30, 1999, and therefore are in effect on Census Day, April 1, 2000; these entities reflect the 1990 metropolitan area standards. 

## Race/Ethnic Detail - Block Level

**Total population**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
At the block level, there are counts for the total population and 45 tables that are tabulated for the 6 major race groups (White, Black or African American, American Indian and Alaska Native, Asian, Native Hawaiian and Other Pacific Islander and Some Other Race) plus “two or more races,” “Hispanic or Latino,” and “White alone, not Hispanic/Latino. “
The tables cover population and housing subjects. These tables are repeated by race, Hispanic origin and by gender.

## SF1 RepeatingTabulations

**SF1 Repeating****Tabulations**

**5-year **
**groupings**

**Notes:**
There are nine repeating tabulations for the population subjects. For example sex by age (Table P12) is tabulated by male and female and by age and race, in five-year groupings (5 to 9 year; 10 to 14 years, etc.). These same tables are then repeated for 9 race and Hispanic groups.
     White alone (Table P12A), 
     Black or African American alone (Table P12B), 
   American Indian and Alaska Native alone (Table P12C),
     Asian alone (Table P12D), 
     Native Hawaiian and Other Pacific Islander alone (Table P12E) and by
     Some Other Race alone (Table P12F),
     Two or More Races alone (Table P12G)
     Hispanic and not Hispanic (Table P12H), and
     White Alone, not Hispanic or Latino (Table P12I)

Tabulation (P15) for the total number of households is also repeated by the 6 major race groups and for Hispanic and non Hispanic (P15A through P15I).
The average household size (P17) is tabulated by number of persons in the household, and by the 6 major race groups (P17A through P17I).
Other repeating tables are available on household relationships, families, and group quarters.

## Examples of SF1 Tabulations

**P1 ****	****Total population**

**P14****	****Sex by age for the population    ****	****	****under 20 (single years of age)**
**P15****	****Households**
**P17****	****Average household size**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Here you see examples of the kinds of tabulations available in Summary File 1 (P is for population). 
Table P1 provides the total population count for the geographic area.
Table P3 provides population counts by 63 single or multiple race categories.
Table P8 shows the number of persons that indicated Hispanic or Latino origin by 7 race categories
P12 shows the number of males and females in 5-year age categories (85 and over is the upper limit).
Table P14 shows the number of males and females in single years of age categories, but only for the population under 20 years.
P15 contains the total number of households; and 
P17 shows the  average household size. 

SPEAKERS NOTES: Tables are labeled: P1, P1A,  PCT1, PCT1A, H1, H11A.

P =  population; P1A = population repeated; PCT1 = population at tract level; PCT1A = population at tract level repeated; H1 = housing; H11A = housing repeated.

## Examples of SF1 Tabulations

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
While many tables are available at the block level, SF1 provides more detailed data on specific (American Indian and Alaska Native, Asian, Native Hawaiian and Other Pacific Islander, Hispanic or Latino) groups. Additional tabulations at the census tract level include single years of age data, compared to data at 5-year age groupings at the block level. 

Group quarters population tabulations by (single years to 99, and 100 to 110 years in 5-year groupings) age and gender are also provided in SF1. Household information is also available at the tract level. 

SPEAKER NOTES: Tables are labeled: P1, P1A,  PCT1, PCT1A, H1, H11A.

SPEAKER NOTES: Why does the census only list 36 categories? What about other tribes?
These are the top 35 American Indian tribal groupings; and see next slide for Alaska Native tribes/tribal groupings. There was a national threshold of 7,000 established in order for data for detailed groups to be shown in Census 2000 data products. The threshold was based on 1990 census results. Many of the individual American Indian and Alaska Native tribes will not meet this threshold, so in an effort to provide some data by tribes census used the tribal group in concept that was used in the 1990 census. Persons reporting other tribes are included in “All other categories” in Summary File 1. Additional detailed data will be available in a separate report on American Indians that will be released later.

## 5 Alaska Native Categories

These are the top 4 Alaska Native tribes/tribal groupings. There was a national threshold of 7,000 established in order for data for detailed groups to be shown in Census 2000 data products. The threshold was based on 1990 census results. Many of the individual American Indian and Alaska Native tribes will not meet this threshold, so in an effort to provide some data by tribes census used the tribal group in concept that was used in the 1990 census. Persons reporting other tribes are included in “All other tribes” in Summary File 1. Additional detailed data will be available in a separate report that will be released later.

## 100-Percent Summary Files

**Summary File 2**
**Almost 50 tables repeated by race, **
**Hispanic/Latino, and American **
**Indian and Alaska Native categories**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Summary File 2 will repeat about 50 of these same tables for several hundred detailed race and Hispanic or Latino-origin groups, and American Indian and Alaska Native Tribes. 

## SF2 Subject Content 

-   **36  Population tables (PCT) at the census tract level**
**  ****11  Housing tables (HCT) at the census tract level**

-     **47 Tables**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Summary File 2 includes population characteristics and housing characteristics. The 100-percent data are presented in 36 population tables (matrices) identified with “PCT” and 11 housing tables identified with “HCT”. 

## SF2 Subject Content 

**Total population**
**132 race groups**
**78 American Indian and Alaska Native tribe categories**
**39 Hispanic or Latino groups**

**250 Population Groups**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Each table is repeated or iterated for 250 population groups: 
• the total population, 
•132 race groups, 
• 78 American Indian and Alaska Native tribe categories (reflecting 39 individual tribes), and 
• 39 Hispanic or Latino groups. 
The presentation of SF 2 tables for any of the 250 population groups is subject to a population threshold of 100 or more people. That is, if there are fewer than 100 people in a specific population group in a specific geographic area, their population and housing characteristics data are not available for that geographic area in SF 2, but would be shown for some higher level of geography.
The upcoming slides show the SF 2 tabulations and what subjects are covered in Summary File 2.

**Notes:**
Here we see a matrix that gives the pros and cons of each method of accessing Census 2000 data. 
Briefly, the File Transfer Protocol method is designed solely for experienced data users who have a vast knowledge of complicated downloads involving segmented files.  
American FactFinder is an easy-to-use, free data tool that all users will find helpful.  AFF is subject to some download limitations though.  

Purchasing CD-ROMs will keep users from having to be on-line to download large amounts of data.  The CD-ROM has a Graphical User Interface (GUI - basically the windows usability format) with preformatted tables, in addition to the data files available in ASCII format.

## File Transfer Protocol (FTP)

- For downloading complete dataset files

## Public Use Microdata Sample Files

**	****Unaggregated records of responses to Census 2000 with all identifying information removed**
**	****Two Files Planned**
**1-Percent National Characteristics File **
**5-Percent State Files **
**100,000 population threshold for geography**
**10,000 population threshold for characteristics**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Researchers who want to do their own cross-tabulations of census information can use a set of data known as the Public Use Microdata Sample Files.

These files are the actual responses to the census questionnaire (in electronic format) but with all identifying information removed.

There will be 2 series of microdata files: a 1-percent National Summary File that will contain the full-range of characteristics from the questionnaire.  Specific states will be identified on the file.

For researchers who need to tabulate data for areas below the state level, there will be a 5-percent file, released on a state-by-state basis, that identifies,  generally, counties or groups of counties that have a population of 100,000 or more.  Some characteristics may not be shown if there are less than 10,000 persons in the country with those characteristics.  In this case some of the categories may be collapsed.

## Demographic Profiles

**100% and Sample Data Profiles**

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
We created a series of “profile” reports for users who want to get an overview of their area.  Profile reports will be available on the Internet and available with the SF1 and SF3 data on the CD-ROM.

## Tables

**Quick Tables **

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Quick Tables present additional key variables for a single geographic area. They will be in a page-size format, suitable for printing. You will be able to choose from approximately 50 standard tables, pick the geographic area and the universe, for example, the total population, the African American population, etc.

## Tables

**Geographic Comparison Tables **

**U****SC****E****N****S****U****SB****U****R****E****A****U**

**Notes:**
Comparison tables enable you to look at several geographic areas at the same time--for example, all states in the U.S. or all counties in a particular state. The format will also be suitable for printing.
