U.S. data analysis: population, housing and income

Original analyses of housing, population change, insurance coverage, education and access to services. Each article connects a concrete question to Census observations, explains what the comparison means, and includes an interactive table with a reproducible download.

Latest data articles

Population age 65 and older: Maine vs. Florida

Compare residents age 65 and older by percentage and count. Maine and Florida illustrate how service planning differs from a demographic share comparison.

College attainment and household income by state

Compare adult bachelor’s degree attainment and median household income across selected states. Inspect the different universes and avoid unsupported causal claims.

How these articles use public data

The analyses use the site’s retained Census ACS 2020–2024 five-year estimates and PEP Vintage 2025 population history. An article’s editorial date is separate from its observation period and its September 30, 2026 data review. A recent article can legitimately explain an older survey period; its headline does not turn that estimate into current-year data.

Source counts, denominator exclusions and release IDs accompany the interactive tables. The data controls recompute only documented calculations and export the selected measure. Photographs illustrate the subject; numerical evidence comes from the Census source tables. Descriptive differences do not establish a causal effect or a statistically resolved ordering.
