American Community Survey Supplemental Data

The American Community Survey (ACS) is an ongoing survey that provides data every year -- giving communities the current information they need to plan investments and services. The ACS covers a broad range of topics about social, economic, demographic, and housing characteristics of the U.S. population.

The supplemental estimates consist of high-level detailed tables tabulated on the 1-year microdata for geographies with populations of 20,000 or more. The intention of this product is to allow people with smaller populations key estimates that are more current than the 5-Year file.

These high-level estimates are available for the nation, all 50 states, the District of Columbia, Puerto Rico, every congressional district, every metropolitan area, and all counties and places with populations of 20,000 or more.

Notes on Supplemental Estimates

Please note that the Supplemental Estimates may return the following in place of data:

An '**' entry in the margin of error column indicates that either no sample observations or too few sample observations were available to compute a standard error and thus the margin of error. A statistical test is not appropriate.

An '-' entry in the estimate column indicates that either no sample observations or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest interval or upper interval of an open-ended distribution.

An '***' entry in the margin of error column indicates that the median falls in the lowest interval or upper interval of an open-ended distribution. A statistical test is not appropriate.

An '*****' entry in the margin of error column indicates that the estimate is controlled. A statistical test for sampling variability is not appropriate.

Notes on Annotation Values

Supplemental Estimates contain variables ending in E, EA, M and MA.

Variable Type	Title	Meaning
E	Estimate	A numeric representation of the estimate.
EA	Estimate Annotation	A character representation of the estimate. If an Estimate Annotation exists, use this value in place of the Estimate.
M	Margin of Error	A numeric representation of the margin of error.
MA	Margin of Error Annotation	A character representation of the margin of error. If a Margin of Error Annotation exists, use this value in place of the Margin of Error.

Examples with Annotations

Example #1:

In the following example, the character value “*****” is returned by K200104_001MA. Using the notes above, this indicates the estimate is controlled.

api.census.gov/data/2016/acs/acsse?get=NAME,K200104_001M,K200104_001MA&for=us:*&key=YOUR_KEY_GOES_HERE

Returns:

[["NAME","K200104_001M","K200104_001MA","us"],

["United States","-555555555","*****","1"]]

Example #2:

In the following example, the character value “-“ is returned for K201905_001EA. Using the notes above, this indicates the estimate could not be calculated.

api.census.gov/data/2016/acs/acsse?get=NAME,K201905_001E,K201905_001EA&for=place:67825&in=state:49=YOUR_KEY_GOES_HERE

Returns:

[["NAME","K201905_001E","K201905_001EA","state","place"],

["Saratoga Springs city, Utah","-666666666","-","49","67825"]]
