accessibility of a given residential neighborhood as a function of its distance
to all job locations within a CBSA, with larger employment centers weighted
more heavily. Specifically, a gravity model is used, where the accessibility
(Ai) of a given residential block- group is a summary description of the
distance to all job locations, with the distance from any single job location
positively weighted by the size of employment (job opportunities) at that
location and inversely weighted by the labor supply (competition) to that
location. More formally, the model has the following specification: <div style='text-align:center;'><img alt='alt text' src='https://cloud.githubusercontent.com/assets/5577360/7684618/7a57467c-fd55-11e4-9332-697262f3a025.png' /><br /></div><div>Where i
indexes a given residential block-group, and j indexes all n block groups
within a CBSA. Distance, d, is measured as “as the crow flies” between
block-groups i and j, with distances less than 1 mile set equal to 1. E
represents the number of jobs in block-group j, and L is the number of workers
in block-group j. </div><div><br /></div><div>The Longitudinal
Employer-Household Dynamics (LEHD) has missing jobs data in all of Puerto Rico
and a concentration of missing records in Massachusetts. <br /><br /></div><div><i><b><font size='3' style='font-family:inherit;'>Interpretation</font></b></i><br /></div><div>Values are percentile ranked with values
ranging from 0 to 100. The higher the index value, the better the access to
employment opportunities for residents in a neighborhood. <div><br /><div><u>Data Source:</u> Longitudinal Employer-Household Dynamics (LEHD) data, 2017. </div><div>Related AFFH-T Local Government, PHA and State Tables/Maps: Table 12; Map 8. <br /><br /></div><div>To learn more about the Jobs Proximity Index visit: </div><div><a href='https://www.hud.gov/program_offices/fair_housing_equal_opp/affh' target='_blank' rel='nofollow ugc noopener noreferrer'>https://www.hud.gov/program_offices/fair_housing_equal_opp/affh</a> ; <a href='https://www.hud.gov/sites/dfiles/FHEO/documents/AFFH-T-Data-Documentation-AFFHT0006-July-2020.pdf' target='_blank' rel='nofollow ugc noopener noreferrer'>https://www.hud.gov/sites/dfiles/FHEO/documents/AFFH-T-Data-Documentation-AFFHT0006-July-2020.pdf</a><span style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'>, for questions about the spatial attribution of this dataset, please reach out to us at </span><a href='mailto:GISHelpdesk@hud.gov' style='color:rgb(0, 97, 155); text-decoration-line:none; font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;' target='_blank' rel='nofollow ugc noopener noreferrer'><b>GISHelpdesk@hud.gov</b></a><span style='font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'>. </span></div><div><br />Date of Coverage: <b>07/2020</b> </div></div></div>
