Survey statistics come from the Census Bureau's American Community Survey, pooled over 2020–2024. They describe that five-year period, not today.
The Census doesn't publish figures for neighborhoods, so we build them from 2 census block groups: 1 lie entirely inside, and 1 only partly, counted by the share of their 2020 Census housing units inside the boundary (41% of homes here sit in those partial block groups).
Margins of error (±) are at 90% confidence, computed from the Census Bureau's 80 variance replicates, so they account for the survey's design. Medians are interpolated from the published brackets. Estimates whose margin is large relative to the value are marked caution (coefficient of variation over 15%) or unreliable (over 30%).
