Outside Sacramento's Shadow: Where the Other 69.0% of California Actually Lives

By SimpleMapLab·Published 13 May 2026·Rank #42 of 50 states·↑ All 50 states

Only 31.0% of California’s population lives within 100 miles of Sacramento. The state’s largest population centre — Los Angeles — sits 366 miles from the capital, far outside the 100-mile circle. California ranks #42 of 50 states for capital centrality, meaning 8 states have a less-misplaced capital.

Why this happened

Sacramento was chosen as California's capital in 1854 — at the time the largest inland city in the state and the gateway to the Sierra goldfields. The decision was sensible for an 1850s California; it is wildly off-centre for the modern state. The 100-mile radius around Sacramento reaches 31.0% of Californians: the Central Valley, the Bay Area's North Bay, and a sliver of the central coast. Los Angeles — the population centre of the state — sits 366 miles south of the Capitol.

California's political geography is dominated by the 500-mile distance between the capital and the state's largest city. Modern California governors typically split residence between Sacramento and a Los Angeles or Bay Area home. The capital itself remains a small political town surrounded by farmland and the Sierra foothills.

The top 5 most-populous places (by aggregated ZIP code population) sitting inside the 100-mile circle around Sacramento. Cities are listed by total population captured by ZIP centroids in the dataset.

#	City	Population in radius

The largest city outside the radius

California’s most-populous city outside the 100-mile circle is Los Angeles, sitting 366 miles from Sacramento. The aggregated population of Los Angeles’s ZIP codes alone — 2,380,896 residents — illustrates the gap between California’s political seat and its population centre.

The Map Radius Tool lets you change the radius (try 50 mi for an urban-suburban question or 250 mi for “a day’s drive”), drag the centre to compare Sacramento’s reach with that of San Jose, or add a second circle for a side-by-side comparison.

Methodology (brief)

We took the lat/lng of the California state capitol building (38.5816°, -121.4944°) and drew a 100-mile geodesic radius. For every ZIP code in California, we tested whether the ZIP centroid falls inside; if so, its population counts. We then divide by California’s total population to produce the percentage. The full methodology for all 50 states is on the hub page.
