In my post on Pennsylvania’s uninsured, I wrote that the Affordable Care Act (ACA) was having little effect in Pennsylvania’s rate of uninsured.  I wrote in another post that I received skeptical comments on my first post. I said in that post that I would look at changes in the rates in other states.  I couldn’t then because the government shutdown also shutdown the US Census Bureau site.  The Advisory Board has come out with an image that can be updated on how many sign up for the state exchanges which are different from the federal.

Now that the shutdown is over I can look at the Census Data for the Small Area Health Insurance Estimates (SAHIE) for states from 2008 thru 2011.  To determine which states had a significant decline in the uninsured rate from 2010 to 2011 (the period where portions of the ACA have taken effect such as the one allowing parents to keep their kids on their insurance until age 26), I marked a state as declined if it had a rate that declined outside its margin of error (MOE).  There were 14 states with a significant change in their rates and 37 (including DC) that either stayed the same or increased.   States with larger populations have smaller margins of error.  

Five of the states are summarized in the graph above, California, Massachusetts (which has it’s version of the ACA), Pennsylvania, Texas (with the largest rate in the US), and Vermont (which is the first in the US to pass a single payer plan).  California, Texas, and Vermont had significant decreases in the rates while Pennsylvania and Massachusetts remained within the margin of error (MOE) for both years.  Missouri was the only state that showed a significant increase from 15.3% to 16.0% which was outside the MOE of 0.3%.

ACA Decrease in uninsured * Medicaid Expansion Crosstabulation
		Medicaid Expansion			Total
		not participating or considering not participating	participating or leaning	expanding through alternate means or considering
ACA Change in uninsured	No	16	15	6	37
	yes	6	8	0	14
Total		22	23	6	51

I tried to see if there was any association between decreases in the rates and other state level variables but there was none.  The table above shows that there is no relationship between a significant decrease in the rate and whether or not the state is participating in Medicaid Expansion (p=0.254).  PA Gov. Corbett has proposed a draconian version of Medicaid expansion which Lloyd Stires has written extensively about.   Below is a table showing where each state stands on the ACA decrease and Medicaid expansion.  I added this clip from The Daily Show to give somewhat amusing background on Medicaid expansion.
