Today, the U.S. Census Bureau, released the latest American Community Survey (ACS) 5-year estimates (2013-2017). These data are the only data available at the census tract and municipal level for Connecticut. We have created a tool that enables you view changes for: median household income, population estimates, population without health insurance, poverty status, and median rent. (User beware: when comparing data overtime using ACS 5-year estimates, only use non-overlapping time periods.) CTData has over 50 ACS datasets that we process and curate and will be updating these datasets over the next couple weeks.
