Transportation Data

Journey to Work

Journey to Work information is compiled by the U. S. Census Bureau for use during the transportation planning process. 1990 and 2000 data derives from the long form questionnaire formerly administered during the decennial Census of Population. Data for years since 2000 derives from data collected as part of the ongoing American Community Survey.  The Journey to Work tables address questions such as where workers live and how they commute to work. The information also serves a variety of transportation planning related purposes, including use in connection with the implementation of the City's Parking and Transportation Demand Management (PTDM) Ordinance.

Open Data

Mode split data citywide and for all census tracts is available through the City' Open Data Portal.  Data has ben complied from the journey to work data sets derived from the 1990 and 2000 decennial censuses and from the 2006 - 2010 and 2012 - 2016 American Community Surveys.  Data is available for three groups.  The Labor Force includes all Cambridge residents who work.  The Workforce includes all persons who work in Cambridge, regardless of place of residence.  The Resident Workforce includes all persons who both live and work in Cambridge.

Moving Forward Report

The report Moving Forward: Cambridge's Journey to Work 2020, analyses American Community Survey data on commuting, which has been collected in the Census Transportation Planning Package (CTPP) together with Local Employer Households Dynamics (LEHD) data collected as part of the unemployment insurance program. The report summarizes the commuting patterns among three cited groups of workers - the Labor Force, all persons who live in Cambridge and work, the Workforce, all persons who work in Cambridge regardless of place of residence, and the Resident Labor Force, those who both work and live in Cambridge. 

The report is based on data collected into the 2012 - 2016 Census Transportation Planning Products (CTPP) data set, the most recent complete analysis of the national transportation data collected by the U. S. Census Bureau, and the 2017 Local Employer Household Dynamics (LEHD) data set. Comparative information is also provided from the 2000 and 2006 - 2010 Journey to Work data sets.
