		"fullDescription": "This data represents the mean travel time (in minutes) to work in Boston. The universe is workers age 16 or older. The data originates from the United States Census Bureau's American Community Survey. The Census Bureau has aggregated individual survey responses to census tract geographies. The LMEC worked with cartographer Daniel Huffman to process the census data. We created a new dataset from the census data to study demographics in Boston. The geography covers the City of Boston. The time coverage reflects 2014-2018 as a five-year average. ",

We documented the new names in a codebook \n 6. We combined the new data tables to the GIS boundary files using GIS software to create the final dataset"
