Data

Census 5-Year ACS Data 2020-2024 at tract geography with an equity index score calculated per tract. Higher scores mean a greater concentration of marginalized communities in the tract. To calculate an index score, several steps were followed: 1) Each percent estimate from the 10 ACS demographic indicators included in the dataset (indicated with a "p" prefix) is assigned a z-score per tract. A z-score quantifies how far above or below the regional average the value is. 2) The ten z-scores are each put on a scale from 0-100 based on minimum and maximum values. This is done to avoid overemphasizing indicators that are simply more variable than others. 3) The ten scaled z-scores are grouped into three domains based on common themes. These domains are Economic Status, Mobility Barriers, and Race & National Origin. For each domain, the mean of the scaled z-scores is calculated creating three domain scores. 4) The three domain scores are averaged to calculate the final index score.
