How to read it
California has about eleven Taiwans of land but not even twice Taiwan’s population.
Geography and shape
Both face the Pacific, and both are long and mountainous: Taiwan’s main island runs about 390 km north to south, while California runs about 1,240 km from the Oregon border to Mexico, with the Sierra Nevada along its east side and the Central Valley in its middle.
Population context
California is the most populous US state, with an estimated 39,355,309 residents on 403,677 km² of land, about 97 per km². Taiwan has 23,299,132 registered residents on 36,197 km², about 644 per km² — roughly 60% of California’s population on 9% of its land.
Boundaries and definitions
Taiwan uses household registration at year-end 2025 and national administrative land area, outlying islands included. California uses the Census Bureau’s Vintage 2025 estimate for 1 July 2025 and the state’s land area, which leaves out 20,289 km² of water such as San Francisco Bay. With that water included, California is about 11.7 Taiwans.
Taiwan: Registered population and official administrative land area.
California: The State of California: 403,676.56 km² of land and 39,355,309 residents. Area is the Census Bureau’s land area (ALAND) for the state in the 2025 Gazetteer, which excludes inland and coastal water — another 20,289 km², so the land-plus-water total is 423,965 km². Population is the Census Bureau’s Vintage 2025 resident estimate for 1 July 2025, not a census count. The outline is Natural Earth’s admin-1 polygon for California, including the Channel Islands, and measures about 1.5% larger than the official land area because its coastline encloses bays such as San Francisco Bay. California uses Pacific Time (UTC−8, UTC−7 in summer).
In-depth guide
How should Taiwan and California be understood in context?
Taiwan and California face each other across the Pacific and are often linked through the technology industry, but they are built at very different scales. California has about 11 times Taiwan’s land and not quite 1.7 times its population.
Eleven Taiwans, sixty per cent of the people
California’s 403,677 km² of land holds Taiwan’s 36,197 km² about 11.2 times. Taiwan’s 23.3 million people are about 59% of California’s 39.4 million, so Taiwan averages about 644 people per km² against California’s 97 — about 6.6 times as dense.
The two share a pattern: a long mountain spine, with people packed along the coast and in lowland basins. In California that means Los Angeles, the San Francisco Bay Area and San Diego; in Taiwan, the western corridor from Taipei to Kaohsiung.
