Equity and Tacoma 2025
Tacoma 2025 represents our community’s vision for Tacoma’s future. With defined indicators and other ways to measure progress, it is a plan that guides where the City of Tacoma – as both a local government organization and a community – is going over the next 10 years. The Equity Index is a significant part of our strategy to connect the City’s strategic goals, council priorities, department initiatives, and other assessments to implement the community's vision.
Determinant Categories
The 32 indicators for each of the five determinant categories of the index (Accessibility, Economy, Education, Livability, and Environmental Health) were meticulously and collaboratively chosen. To create the calculations behind Tacoma Equity Index, we collaborated with the Kirwan Institute to select an array of community indicators of well-being, each of which has been shown in the social sciences literature to influence one's ability to succeed in life. The data for these indicators were collected at or aggregated to the Census Block Group level, and roll up to the overall Equity Index into a single measure based on several factors that can be compared across the city.
Data Limitations and Diving Deeper
Part of the value of building an opportunity index is identifying the most accurate sources of data available. This can be a tedious process, but creating an opportunity index with the most accurate information at the most detailed geographic level will ensure confidence in the mapping products. However, another essential part of this process is recognizing the available dataset's limitations and moving forward. Perfect data rarely exists; though we care about understanding margins of error, confidence intervals, and collection methodologies, recognizing and accepting data shortcomings is part of the process.
Once the maps reveal high and low opportunity areas, we caution against a shallow analysis on the data and what the maps show when thinking through policy, investment, or program implications. For example, areas that show up as high opportunities should not be regarded as not needing any investment, as a deeper dive for example may show they have great natural amenities, but lack employment opportunities. Relying solely on the quantitative-based data used in the maps is not enough to make investment decisions. It is dependent on us to dive deeper into this data and tell a compelling story as to why a policy and/or program is the right one to address inequities in that area of Tacoma.
