2019 Annual Affordability Refresh
2019 Annual Affordability Report
The 2019 Annual Affordability Report highlights trends in the affordability of households’ essential electric, gas, water, and communications services. The report provides a geographically-focused assessment using these three metrics: affordability ratio (AR), hours at minimum wage (HM), and socioeconomic vulnerability index (SEVI).

Affordability Ratio Calculator
The Affordability Ratio Calculator (ARC) is an annually updated Excel-based calculator that will be pre-populated with the values needed to calculate the Affordability Ratio (AR) for representative households at the 20th and 50th percentiles of the income distribution within each PUMA based on the most recently available socioeconomic, essential usage bills, and forecast data.

Metrics Data and Interactive Maps
Below are the downloadable tabular files, interactive maps, and raw data work papers of the three metrics.
The Affordability Ratio (AR) metric quantifies the percentage of a representative household’s income that would be used to pay for an essential utility service, after non-discretionary expenses such as housing and other essential utility service charges are deducted from the household’s income. The higher an AR, the less affordable the utility service. The AR may be calculated for a single essential utility service, a combination of services, or all essential utility services combined.
Hours at Minimum Wage
The Hours at Minimum Wage (HM) metric quantifies the hours of earned employment at the city minimum wage necessary for a household to pay for essential utility service charges. The minimum wage-based metric also implicitly considers the impact of essential utility service charges on lower-income customers regardless of the socioeconomic conditions of the community as a whole.
Socioeconomic Vulnerability Index
The Socioeconomic Vulnerability Index (SEVI) metric represents the relative socioeconomic standing of census tracts, referred to as communities, in terms of poverty, unemployment, educational attainment, linguistic isolation, and percentage of income spent on housing. This metric therefore considers how a rate change may affect one community’s ability to pay more than another’s.
