ACS and Census Questions
about the data
About the 2006 ACS data release

Used only Single-year estimates

Populations of 65,000+

Decisions about data release applied at the table-level

Full detail or collapsed data based on the reliability of the estimates in each table

Included guidance on comparisons and other resources

Housing units and group quarters

About the Data
about the data9
About the 2007 ACS data release

Will use both single and multiyear estimates

Single year for populations of 65,000+

Multiyear for populations of 20,000+

Decisions about data release probably applied at the table-level

Full detail or collapsed data based on the reliability of the estimates in each table

Will included guidance on comparisons and other resources

Will include housing units and group quarters

About the Data
about the data10
Other points about the 2007 ACS data release

Most data products will be identical to 2006 data release

Data profiles will add estimates in percent format

Selected population profiles will be expanded to include iterations by country of birth

Some year-to-year comparisons

Subset of data profiles will compare 2007 ACS with 2006 ACS results

Will include flags for statistical testing results

About the Data
about the data11
At least it’s not all coming at the same time*

1-Year Estimates

August 26, 2008 release of 2007 ACS estimates on income, earnings, and poverty

September 23, 2008 release of 2007 ACS estimates on all other topics

3-Year Estimates

December 2008 release of 2005-2007 ACS estimates on all topics

About the Data
about the data12
About those 3-year estimates

Types of geographic areas receiving 3-year estimates are essentially same as those receiving 1-year estimates (state, county, place, etc.)

Estimates are based on

Housing unit population data from 2005, 2006 and 2007

Group quarters population data in 2006 and 2007

Estimated 3rd year values by weighting ’06 and ‘07

Will use actual group quarters data in future years

About the Data
geography
Under the 2006 ACS

Approximately 5,650 geographic areas qualified for reporting single year data

Under the 2007 ACS

Approximately 5,650 geographic areas will qualify for reporting single year data

Approximately 12,300 geographic areas will qualify for reporting three year data

Estimated total of 17,950 geographic data sets to review

As Census 2010 approaches, there is a strong and pressing burden on those who understand statistics to educate

Policy makers

The media

The public

Ourselves

About

Statistical significance

Margin of error

Definitional differences

The Educational Burden

the educational burden
Sample Size

2006 ACS

Sampled approximately 3 million housing units (HU)

Yields about 2.19 million interviewed HU (21.9 over 10 years)

Sampling rate of approximately 2.4% of HU

Approximately 1 in every 40 HU annually

2000 Census Long Form

Sampled slightly less than 20 million HU

Yielded about 19.2 million interviewed HU

Sampling rate approximately 17.0% of HU

Approximately 1 in every 6 HU

The Educational Burden
the educational burden31
The trade-off

Yes, we don’t have to wait every 10 years for data

But, there is a larger margin of error

Because sample size is smaller

Because data collection is spread over multiple years

Inflationary impact

Boundary changes

Etc.
