[Excerpt] Today, the Census Bureau began releasing local-level Connecticut data from the 2010 Census. You may refer to the DataHaven Knowledge Center for a file showing the population growth in Connecticut's counties and largest cities. DataHaven also has a number of resources related to the 2010 Census, including more documents and interactive map-based visualizations, on this page (a newer web browser may be required to see the maps). Visualizations by race and ethnic group for Connecticut Census data can be seen here.
