The worker-weighted access here represents the average number of jobs a person can reach from a specific census area within a given travel time threshold, by walking or rolling using a personal mobility device such as a wheelchair. The travel time threshold are in integer minutes, at five-minute intervals from 5 min to 60 min (1 hour). Census levels included in this dataset are: Block, Block Group, Census Tract, County, and State. The file-naming system for the data files is [state]_[statecode]_[mode]_[census_level]_[year].csv: These files contain the census level data by mode, year. **Important Note: Due to its large size, the 'Block' level data file should not be opened outside of a person's coding platform. Attempting to open this file in Excel or a similar spreadsheet program would cut off a significant amount of data points.** Data fields included in the data are: 1. mode: the type of travel modes, one of auto, bike, wallk, or transit; 2. year: National Accessibility Evaluation data year, the year for which this dataset is relevant; 3. parent_area: the ID of the containing geography within which the data averages are calculated; 4. summary_level: the level of geography at which averages are calculated - one of state, county, census tract, block group, or block; 5. geoid: the ID of the particular census geography for which the data averages are calculated; 6. threshold: the travel time threshold in minutes, ranging from 5 to 60 minutes; 7. weighted_average: the average number of jobs a person can reach from a given census area within the travel time threshold for a specific mode. The LODES dataset used to calculate jobs in this data does not include job location data from the states of Alaska, Arkansas, or Mississippi. Therefore these states are not included in this data archive. See documentation at https://lehd.ces.census.gov/data/lodes/LODES8/LODESTechDoc8.1.pdfThese data were created as part of a study that examines the accessibility to jobs by walking or rolling across the United States. It is the most detailed evaluation to date of access to jobs by walking, and it allows for a direct comparison of the walkability of America's metropolitan areas. These data are part of a longitudinal study.
