Census Publishes Commuting Data for Massachusetts!

We are super excited at The Public Policy Center that Massachusetts has finally joined the rest of the country in releasing the data that is used in the production of two important Census Bureau data products: Longitudinal Employer-Household Dynamics (LEHD) and LEHD Origin-Destination Employment Statistics (LODES). The LODES data will be instrumental in a recently launched study of the economic connections between southeastern Massachusetts and Rhode Island by allowing us to look at commuting patterns at the city and town level (formal announcement forthcoming). This data was just released yesterday afternoon and I’ve had a lot of fun playing around with the data via the Census’s OnTheMap tool. Here are a couple of the data visualizations that I produced using OnTheMap:

This first image shows the inflows and outflows for the Southcoast of Massachusetts in 2014 (defined here to include Swansea, Somerset, Fall River, Westport, Dartmouth, Freetown, New Bedford, Acushnet, Fairhaven, Mattapoisett, Rochester, Marion, and Wareham). According to the LODES data, 41,463 people who work on the Southcoast live elsewhere, 66,613 people who live on the Southcoast work elsewhere, and 76,289 people both live and work on the Southcoast.

This next image shows the distance, direction, and volume of commutes into the Boston Workforce Investment Area. The color indicates distance and the size of each slice indicates volume. This graph suggests that the greatest number of people commute from South of Boston, while people to the West and Southwest travel the longest distances. In 2014, an estimated 6,844 people commuted from the Southcoast to the Boston Workforce Investment Area. Meanwhile, 8,192 commuted from the Southcoast to the workforce investment area for Greater Rhode Island.

Now it’s time to learn how to work with the raw data so I can develop customized data processing algorithms. Fun!
