The Low Transportation Cost Index is based on estimates of transportation expenses for a 3-person single-parent family earning 50% of the median income for renters in the surrounding region (i.e. Core-Based Statistical Area). The estimates come from the Location Affordability Index (LAI). The data correspond to those for household type 6 as noted in the LAI data dictionary. More specifically, among this household type, we model transportation costs as a percent of income for renters. Neighborhoods are defined as census tracts. The LAI data do not contain transportation cost information for Puerto Rico.

LOW TRANSPORTATION COST INDEXSummaryThe Low Transportation Cost Index is based on estimates of transportation expenses for a family that meets the following description: a 3-person single-parent family with income at 50% of the median income for renters for the region (i.e. CBSA). The estimates come from the Location Affordability Index (LAI). The data correspond to those for household type 6 (hh_type6_) as noted in the LAI data dictionary. More specifically, among this household type, we model transportation costs as a percent of income for renters (t_rent). Neighborhoods are defined as census tracts. The LAI data do not contain transportation cost information for Puerto Rico.InterpretationValues are inverted and percentile ranked nationally, with values ranging from 0 to 100. The higher the transportation cost index, the lower the cost of transportation in that neighborhood. Transportation costs may be low for a range of reasons, including greater access to public transportation and the density of homes, services, and jobs in the neighborhood and surrounding community.
