Every US metropolitan statistical area on the July 2023 OMB delineations. Pick a measure, then hover or tab to a metro. All values are computed from Census Bureau Vintage 2025 population estimates; the same numbers are in the table below the map.
Alaska and Hawaii are reprojected into their own Albers zones and inset at the lower left rather than dropped; the frame is a composite display space, so distances on it are not meaningful. Puerto Rico and micropolitan areas are excluded. Group quarters are retained in the age measures shown here. Sequential ramps run light→dark in light mode and dark→light in dark mode so that "high" is always the step furthest from the page surface; the cohort ratio uses a diverging ramp with a neutral midpoint at 1.0, its meaningful centre.
