Precinct demographics
Demographics are Census American Community Survey (ACS) 2020-2024 5-year estimates for block groups, assigned to precincts by area share. They describe the resident population, not registered or likely voters, and include non-citizens. ACS margins of error are not shown; small precincts carry large error. Area weighting assumes people are spread evenly within each block group, so large rural precincts are the least reliable. Median income is a household-weighted average of block-group medians, an approximation.
