Tulsa Equality Indicators scores indicators in two ways: 1) a static equality score indicating the amount of disparity between the two population groups, and 2) a change score indicating the amount of change in the equality score from baseline to present.
Static equality scores at higher levels are created by averaging the scores one level below them. This means that static topic scores are comprised of the average of their three indicators and static theme scores are comprised of the average of their three topics. The six themes are averaged to produce the static citywide score each year. The intentional even distribution of indicators across themes ensures that every theme has equal weight in the calculation of the overall city score.
Every indicator receives a score ranging from 1, representing full inequality, to 100, representing full equality, based on the disparity between the two populations compared. In general, the two comparison groups for each indicator represent the most and least disadvantaged populations for that specific indicator, based on rates calculated using the latest population data from the U.S. Census Bureau. The greater the difference between the two groups, the lower the equality score; the smaller the difference, the higher the score.
