About the American Community Survey
The ACS is a household survey that began in 2005 and produces annually updated data on a variety of population characteristics, including health insurance coverage. In total, the ACS surveys approximately three million US households each year.
An important feature of the ACS is that it includes a large enough sample for state‐level and sub‐state estimates such as the estimates in this analysis.
Note: Federal Poverty Levels
For this analysis, estimates are provided for houshold incomes that are: below 138% of the Federal Poverty Level (FPL); from 138% FPL to 199% FPL; from 200% FPL to 399% FPL; and at or above 400% FPL. In Medicaid expansion states, individuals are eligibile for Medicaid eligibility at incomes below 138% FPL. The limit for premium subsidies for coverage purchased through the Marketplace is 399% FPL. The following table provides 2015 FPL dollar amounts for key income thresholds used in this analysis.
|Ratio of Income to 2015 Federal Poverty Level (FPL)|
|138% FPL||200% FPL||399% FPL|
|Family of Four||$33,475||$48,514||$96,785|

*The income cuts used in this analysis are slightly different than ACA eligibility levels because of how data are tabulated in American FactFinder, but the differences are negligible. Although Medicaid eligibility for the expansion population covers people with incomes at or below138% FPL, this analysis groups incomes below 138% FPL. The scenario is similar for premium subsidy eligibility. This analysis groups incomes below 400% FPL, but people with incomes up to and including 400% FPL are eligible for premium subsidies
