Commonwealth Stats

This tool provides users the ability to find specific demographic data1 for the counties and prominent cities and towns they serve including income, age, education level, race, ethnicity, and language. It also allows users to compare that demographic data between counties and prominent cities and towns and against the overall state data. Through this tool, users will also be able to download datasets and create charts to use for grant proposals, websites, social media, and more.

MNN continues to develop this tool to provide members with more detailed information about the areas and populations they serve. Please try out this this tool and provide us with feedback on how user friendly it is, any problems you encountered, and what other information would be useful for your organization.
