**1. INTRODUCTION AND BACKGROUND**

To reduce the operational complexity of the decennial census and
increase the timeliness of detailed population and housing data, the
Census Bureau has implemented the 2010 Census re-engineering strategy.
One component of this re-engineering strategy is the American Community
Survey (ACS). The ACS is designed to collect long form data throughout a
decade, thereby eliminating the need for a decennial census long-form
sample.

The replacement of the Census sample with the ACS has raised questions
concerning the operational feasibility of the ACS and the reliability
and usability of ACS data. To help answer these questions, the U.S.
Census Bureau has conducted and continues to conduct research in this
area. In 1994 the Census Bureau initiated the ACS development program to
develop methods for providing long form data each year. Since then the
ACS development program has produced reports that demonstrate the
operational feasibility of the ACS as well as the reliability and
usability of ACS data. Research objectives have continued more recently
through the implementation of an ACS Research and Evaluation Program. As
part of this research objective, we will be producing a report to help
data users understand how the quality of the ACS 3-year average data
(average of 1999 ACS, 2000 ACS, and 2001 ACS) compare to the Census 2000
long form data.

To allow for comparisons of quality, we provide quality measures and
their standard errors for the 36 ACS counties and tracts in the ACS test
sites. This document describes the computation of the quality measures
and their associated standard errors.

1.  **Census 2000 Sample**

Census 2000 collected data using two basic types of questionnaires---the
short form, containing only the "100%" items asked of the entire
population, and the long form, containing the "100%" items as well as a
myriad of detailed housing unit, household, and population items known
as sample items. The "100%" items were name, relationship, sex, age,
Hispanic origin, race, and tenure for occupied housing units, and
vacancy status for vacant housing units. A national average of about
one-in six housing units were expected to be enumerated on the long form
and make up the Census 2000 sample; the other five-sixths of the
addresses were to be enumerated on the short form.

This comparison project is based on characteristic distributions as
estimated by the Census 2000 sample, and additionally on information
reflecting overall response to the Census 2000 long form questionnaire.
Not all units enumerated on long form questionnaires are eligible to be
members of the Census 2000 sample. To be eligible for inclusion, long
form response records representing occupied housing units (or
households) had to meet a set of criteria identifying them as 'sample
data defined.' The household records had to contain at least one person
who was both "100%" data defined and sample data defined. To satisfy
these criteria a person record had to have answers to at least two of
the "100%" population items and two of the sample population items. No
answers to any housing items were required of occupied long form units
to be considered census sample-eligible. For vacant long form units to
be placed in the Census 2000 sample they had to have answers to at least
two housing sample items.

In addition to estimates based on housing units and the household
population, the Census 2000 sample also included data from the group
quarters population. These records were removed from the sample for this
analysis. All but one of the Census 2000 quality measures included in
this study are based on information directly affecting the sample. The
one exception is the long form questionnaire self-response rate, which
is based on the form counts from the full census count process.

Susan P. Love of the U.S. Census Bureau contributed the information
given in this section.

2.  **ACS Sample**

The ACS has continuous, monthly samples, where each sample has a
three-month collection cycle . Samples in each cycle uses a combination
of mailout/mailback questionnaires, Computer Assisted Telephone
Interviewing (CATI), and Computer Assisted Personal Interviewing (CAPI)
to collect ACS data.

ACS samples were selected using variable sampling rates, which generally
paralleled Census 2000. For the 1999, 2000, and 2001 ACS, most of the 36
counties were sampled at an annual rate of five percent. The exceptions
were the larger counties. Specifically, for Fort Bend and Harris
Counties, Texas, the overall housing unit sampling rate was one percent.
For Broward County, Florida; Bronx County, New York; Lake County,
Illinois; San Francisco County, California; and Franklin County, Ohio,
the overall housing unit sampling rate was three percent. The sampling
rate within the county varied by the size of the governmental unit in
which the housing unit was located (Bureau of the Census, March 2003).

Eventhough the ACS sampling rates paralleled the Census 2000 sampling
rates, they were not the same. There were two reasons for this. First,
the ACS used total housing unit counts to determine sampling rates;
Census 2000 used estimates of occupied housing units (which was based on
1990 block vacancy rates) . This was a source for different differential
sampling rates between the ACS and Census 2000 in all 36 counties.
Second, only Census 2000 used minor civil divisions (MCD) to determine
the size of governmental units (in areas with MCDs). This was a source
for different differential sampling rates between the ACS and Census
2000 in areas with MCDs.

The one percent sampling rate in Fort Bend and Harris Counties, Texas
yielded small sample sizes at the tract level. Tract estimates based on
these small sample sizes are not representative of the five-year
averages that will be produced at full ACS implementation levels. The
standard errors based on the one percent sampling rate are much larger
than the five-year average standard errors will be, and therefore, are
not representative of the ACS.

**2. QUALITY MEASURES**

We compute the following four quality measures.

-   Self-Response Rates

```{=html}
<!-- -->
```
-   Sample Unit Nonresponse Rates

-   Item Allocation Rates

-   Sample Completeness Rates

Descriptions of each quality measure are given in section 2.1 thru 2.4,
respectively. The descriptions in these sections are written in terms of
the variables appearing on the quality measures data files. To learn
more about these data files and the variables mentioned in sections 2.1
thru 2.4, see "Census 2000 Long Form Data and ACS 3-year Averages
Quality Measures Comparison Data file Layouts" or "qmfiles.doc".

Susan P. Love of the U.S. Census Bureau contributed the descriptions of
the quality measures.

1.  **Self-Response Rates**

Self-response rates are provided for each of the 36 ACS counties, and
for each tract in the 36 ACS counties, regardless of the number of units
in the tract. In addition to the self-response rates, the numerators and
denominators for each rate for each county and tract are provided. If
the denominator of the rate is zero, the rate is shown to be missing on
the file.

*2.1.1 Census 2000 Long Form Self-Response Rates*

Census 2000 long form self-response rates are based on the 100 percent
counts of occupied long form housing units enumerated in mailback types
of enumeration areas (TEA)[^1]. Counts are weighted by the reciprocal of
the sampling fraction used to designate long form sample units (BSAM)
for the block in which they were enumerated. The BSAM values are 2, 4,
6, and 8. The weighted block level long form units are aggregated to the
tract level, and the rates computed from the weighted tract counts. The
self-response rate formula is below.

  ---------- ---- ---------------------------------------------------------
  cen_srr    =    Census long form self-response rate

  cen_srhu   =    Census BSAM weighted count of occupied self-response long
                  form housing units enumerated in mailback TEAs
                  (numerator)

  cen_olhu   =    Census BSAM weighted count of occupied long form housing
                  units enumerated in mailback TEAs (denominator)
  ---------- ---- ---------------------------------------------------------

*2.1.2 ACS Single Year and 3-Year Average Self-Response Rates*

ACS 3-year average self-response rates are based on the base weighted
(WSSF) occupied housing unit counts, including the base weighted
noninterview units. The self-response rate formula is below.

  ---------- ---- --------------------------------------------------------
  acs_srr    =    ACS 3-year average self-response rate

  A99_srr    =    ACS self-response rate for 1999

  A99_srrn   =    ACS WSSF weighted count of occupied self-response
                  housing units including self-response noninterviews
                  (numerator) for 1999

  A99_srrd   =    ACS WSSF weighted count of total occupied housing units
                  including noninterviews (denominator) for 1999

  A00_srr    =    ACS self-response rate for 2000

  A00_srrn   =    ACS WSSF weighted count of occupied self-response
                  housing units including self-response noninterviews
                  (numerator) for 2000

  A00_srrd   =    ACS WSSF weighted count of total occupied housing units
                  including noninterviews (denominator) for 2000

  A01_srr    =    ACS self-response rate for 2001

  A01_srrn   =    ACS WSSF weighted count of occupied self-response
                  housing units including self-response noninterviews
                  (numerator) for 2001

  A01_srrd   =    ACS WSSF weighted count of total occupied housing units
                  including noninterviews (denominator) for 2001

**2.2 Sample Unit Nonresponse Rates**

Sample unit nonresponse rates are provided for each of the 36 ACS
counties, and for each tract in the 36 ACS counties, regardless of the
number of units in the tract. Sample unit nonresponse rates are also
calculated for occupied housing units. In addition to the sample unit
nonresponse rates, the numerators and denominators for each rate for
each county and tract are provided. If the denominator of the rate is
zero, the rate is shown to be missing on the file.

*2.2.1 Census 2000 Sample Unit Nonresponse rates*

Census 2000 sample unit nonresponse rate are based on the comparisons of
the number of long form sample data defined units weighted by their
probabilities of selection and the 100% housing unit counts. The long
form units that met the criteria to be in sample are multiplied by the
BSAM value for the block in which they were enumerated. The sample unit
nonresponse rate formulae are below.

  ----------- ---- --------------------------------------------------------
  cen_unr     =    Census 2000 sample unit nonresponse rate

  cen_tothu   =    Census 2000 total housing units

  cen_ddhu    =    Census 2000 BSAM weighted count of long form sample data
                   defined housing units
  ----------- ---- --------------------------------------------------------

![](media/image7.wmf)

######## Occupied sample unit nonresponse rates

  ----------- ---- --------------------------------------------------------
  cen_ounr    =    Census 2000 occupied sample unit nonresponse rate

  cen_occhu   =    Census 2000 occupied housing units

  cen_oddhu   =    Census 2000 BSAM weighted count of long form occupied
                   sample data defined housing units
  ----------- ---- --------------------------------------------------------

![](media/image8.wmf)

The numerators of these formulae represent the shortage in the Census
2000 sample of housing units due to response records for long form units
not being sample data defined. They are expressed as percents of total
enumerated units.

Occupied census long form units are data defined (SDD) if they have at
least one person record that has at least two 100% population items and
two sample population items answered.

*2.2.2 ACS Single Year and 3-Year Average Sample Unit Nonresponse Rates*

These are based on the base weighted (WSSF) total housing unit counts,
including the base weighted noninterview cases. The sample unit
nonresponse rate formulae are below.

######## Sample unit nonresponse rates

                  (numerator) for 1999

  A99_unrd   =    ACS WSSF weighted count of total (interview plus
                  noninterview) housing units (denominator) for 1999

  A00_unr    =    ACS sample unit nonresponse rate for 2000

  ----------- ---- --------------------------------------------------------

![](media/image13.wmf)

![](media/image14.wmf)

![](media/image15.wmf)

![](media/image16.wmf)

ACS occupied units are noninterviews if they fail the survey's
Acceptability Index (AI). This index is computed by summing the number
of basic items with answers (age or complete date of birth entry count
as two), and then dividing this sum by the number of household members.
Occupied with AIs of less that 2.5 are treated as survey noninterviews.
Note, that all vacant units are considered interviews in the ACS. So,
A99_ounrn equals A99_unrn, A00_ounrn equals A00_unrn, and A01_ounrn
equals A01_unrn.

**2.3 Item Allocation Rates**

To calculate item nonresponse, we calculated item allocation rates. They
are provided for each of the 36 ACS counties, and for each tract in the
36 ACS counties, regardless of the number of units in the tract. At the
county level, the item allocation rates are also broken out by response
mode. They are not broken out by response mode at the tract level. In
addition to the item allocation rates, the numerator and denominator of
the rate for each county and tract are provided. If the denominator of
the rate is zero, the rate is shown to be missing on the file.

There are two response modes: self-response and interviewer-response.
Self-response means that the household data came from a mail return, and
interviewer-response means that the data came from a follow-up form or
instrument. For Census 2000, the follow-up operations were Nonresponse
follow-up and Coverage Improvement Follow-up, and for the ACS the
follow-up operations were Computer Assisted Telephone Interviewing
(CATI) and Computer Assisted Person Interviewing (CAPI).

*2.3.1 Census 2000 Sample Item Allocation Rates*

Census 2000 sample item allocation rates are based on the final-weighted
allocations made by the census edit and allocation process on all
records placed in the Census 2000 sample (on the Census 2000 Sample
Census Edited File or SCEF). We calculated these rates only for census
items that had an ACS item in common; these items and their associated
edit outputs are described in Attachment 1. The item allocation rate
formulae are below.

**2.4 Sample Completeness Rates**

Sample completeness rates are provided for each of the 36 ACS counties
only. They are not computed at the tract level. We provided housing unit
completeness and household population completeness rates. In addition to
these two sample completeness rates, the numerators and denominators for
each rate for each county are provided. If the denominator of the rate
is zero, the rate is shown to be missing on the file.

*2.4.1 Census 2000 Sample Completeness Rates*

Census 2000 sample completeness rates are based on the comparison of the
number of long form sample data defined units versus their populations,
where the populations are weighted by their probabilities of selection
to the 100 percent housing unit and household population counts. The
long form units that met the data criteria to be in sample are
multiplied by the BSAM value for the blocks in which they were
enumerated. These units' household populations are also multiplied by
the BSAM value and compared to the 100 percent counts of the household
population. All calculations are at the county level only. The sample
completeness rate formulae are below.

**3. STANDARD ERRORS**

The standard errors of the Census 2000 and ACS 3-year averages quality
measures are described in this section. Section 3.1 describes the
calculation of the Census 2000 quality measures' standard errors. They
were computed using the Census 2000 published design factors. Section
3.2 describes the calculation of the ACS 3-year average quality
measures' standard errors. For the ACS, the single year estimates were
obtained directly via a replication method, and then used to calculate
the ACS 3-year average standard errors.

**3.1 Standard Errors for Census Quality Measures**

To estimate standard errors for the Census 2000 quality measures, we
applied Census 2000 long form data variance estimation procedures. The
standard errors for the Census 2000 self-response rates, sample unit
nonresponse rates, and item allocation rates were calculated as
described below.

![](media/image42.wmf)

Number range CHAPTERwhere DF is the design factor, B is the base of the
percentage or denominator of the rates shown in sections 2.1 through
2.3, and![](media/image43.wmf) is the rate × 100. For these standard
errors, if ![](media/image44.wmf) was less than 2 percent or greater
than 98 percent, then ![](media/image45.wmf)was set to 2 percent. Also,
any of the standard errors greater than 70 were set to 70.

The standard errors for the Census 2000 sample completeness rates as
were calculated as described below.

![](media/image46.wmf)sample completeness rate

![](media/image47.wmf)

where, ![](media/image48.wmf) is an actual population count, and
therefore has no standard error. ![](media/image49.wmf) is the Census
2000 total housing units for the housing unit sample completeness rate,
and the Census 2000 total household population for the household
population sample completeness rate. Therefore,
![](media/image50.wmf)was treated as a constant in the sample
completeness rate standard errors.

![](media/image51.wmf)

Number range CHAPTERwhere, N is the size of the publication area or in
this case ![](media/image52.wmf), and DF is the design factor.

It should be noted that the formulae for ![](media/image53.wmf)and
![](media/image54.wmf)are derived from the simple random sample variance
for a total with a 1-in-6 sampling rate. In addition, the method used to
calculate ![](media/image55.wmf) underestimates (overestimates) the
standard error if the two items in the rate are negatively (positively)
correlated. For more information on the Census 2000 long form variance
procedures, see the Summary File 3 Technical Documentation, released in
2003. This can be found on the U.S. Census Bureau web site at
http://www.census.gov/prod/cen2000/doc/sf3.pdf .

*3.1.1 Design Factors*

Design factors used in the Census 2000 long form variance procedure are
ratios of the estimated standard errors to the standard errors of a
simple random sample. These factors reflect the effects of the actual
sample design and the complex ratio estimation procedure used for Census
2000 (Summary File 3 Technical Documentation, 2003). There are published
Census 2000 design factors for a wide range of housing unit and
population characteristics (Asiala, 2002). These design factors are
available for each state and the United States, and are calculated by
the Number range CHAPTERfour levels of percent in-sample (observed
sampling rate). The characteristics for which design factors are
published can be found in the Summary File 3 Technical Documentation.
The four levels of percent in-sample are:

-   Level 1 - less than 15 percent

-   Level 2 - 15 percent to less than 25 percent

-   Level 3 - 25 percent to less than 35 percent

-   Level 4 - 35 percent or more

    To calculate the standard errors for the Census 2000 long form
    quality measures, we first identified the appropriate design factors
    to use in the equation. The first step was to identify the
    appropriate percent in-sample level for each of the 36 counties and
    tracts. The percent in-sample for varying geographic levels is
    available on the Census Bureau web site. Attachment 2 contains a
    list of the percent in-sample levels for each of the 36 counties.
    For the tract level quality measures, we used the percent in-sample
    of the tract.

    The second step was to select the design factors that best
    corresponded to the housing or population characteristics. Some
    characteristics had no directly corresponding design factor. We
    determined each characteristic's design factor by::

```{=html}
<!-- -->
```
-   associating the characteristic with a corresponding published design
    factor;

or

-   associating the characteristic with the largest published design
    factor for its corresponding state, and applying this design factor
    to the quality measure values for the counties and tracts that lie
    within a state. Using the largest published design factor provided a
    conservative standard error estimate.

Attachment 3 contains a list of the quality measures and the housing or
population characteristic group whose design factor we used to calculate
standard errors for the quality measures. The national and state design
factors can be found in chapter 8 of the Summary File 3 Technical
Documentation.

Number range CHAPTER**Number range CHAPTER3.2 Standard Errors for ACS
Quality Measures**

For the ACS quality measures, the single year quality measures and
standard errors were computed first. That is, the 1999, 2000, and 2001
quality measures with their associated standard errors were computed
separately first. Then they were combined to produce the 3-year average
quality measures and their standard errors. The standard errors for the
single year quality measures were obtained directly via a replication
method. The standard errors (SE) for the 3-year average quality measures
were then computed as follows. Michael Starsinic of the U.S. Census
Bureau provided the information in this section.

Let ![](media/image56.wmf) , where N stands for numerator and D stands
for denominator.

Year = 1999, 2000, or 2001

![](media/image57.wmf) and ![](media/image58.wmf)

![](media/image59.wmf), ![](media/image60.wmf)

![](media/image61.wmf)

![](media/image62.wmf)

![](media/image63.wmf)

If N~Year~=0 or D~Year~=0 for a given rate, then their rates' standard
errors were calculated as zero using the replication method. Also, a
nonzero estimate sometimes had a zero standard error calculated using
the replication weights. What happened in these cases? We used the
following approximation:

![](media/image64.wmf)

Number range CHAPTERwhere the average weight is the maximum of the
average person and average household final weights for observations in
the county for that year.

When several of the single year estimates have been approximated this
way, the standard error of the three-year average rate can be quite
large. The files have been set up to allow users to handle these SEs
differently if they choose to do so. The quality measure source data
files retain the calculated zero SEs. The three-year average standard
errors incorporate the approximation above for zero SEs, and the quality
measure source data files include the average weights for the three
years.

If D~3yr~ = 0, meaning there were no observations in the denominator for
any of the three years, the standard error for the three year average
rate is set to missing.

If the value calculated for SE(Rate~3yr~) was greater than 70, the
standard error of the three-year average rate was set to 70.

3.  **Standard Errors for the Differences between the ACS and Census
    Quality Measures**

The standard errors for the differences between the ACS and Census
quality measures were calculated as follows.

![](media/image65.wmf)

where difference = Rate~ACS3yr~ - Rate~Census~

It should be noted that the standard error of the difference does not
take into account the covariance between the ACS quality measure and the
Census quality measure. So, this method overestimates the standard error
of the difference.

For the item allocation rates, the following table lists the items for
which an allocation rate will be calculated, and the population/housing
characteristic group which most relates to that item. The design factor
for the population/housing characteristic group listed would then be
applied to the item allocation rate standard errors. The bold housing
unit allocation rate items are vacant housing units items.
