San Jose Authority
Also known as: Sanjose Metro Authority
San Jose is a high-income, family-oriented mid-sized city of 990,138 with home prices 1.7× the California median.
San Jose is the kind of place that surprises people who have not looked at it carefully. It is the largest city in the San Francisco Bay Area by population, larger than San Francisco itself, and yet it occupies a peculiar position in the public imagination — often described as a suburb of somewhere else, which is a description that does not survive contact with the numbers. According to Census ACS 5-Year 2024 data, San Jose's population stands at 990,138, making it one of the fifteen largest cities in the United States, situated in Santa Clara County in the southern reach of the Bay.
Population and Demographics
The Census ACS 5-Year 2023 data places San Jose's total population at 990,138, distributed across 326,767 households, of which 233,068 are family households. The city's demographic composition is notably diverse: the Asian population accounts for 382,011 residents, the Hispanic or Latino population for 306,450, the white population for 287,180, and the Black population for 28,843. These are not rounded estimates — they are the figures the Census Bureau reports at the place level.
The median age, per Census ACS demographics, is 38.2 years. Children under 18 number 202,568, representing 20.5 percent of the population, a share that gives the city what the derived demographic data characterizes as a family-oriented character. The 18-to-34 cohort numbers 244,078, and the 35-to-64 cohort accounts for the largest single age band.
Housing and Affordability
Housing in San Jose occupies a position that is, depending on one's perspective, either a testament to the region's economic vitality or a fairly stark illustration of what happens when demand persistently outpaces supply. Derived from Census income, housing, and poverty data, the home-price-to-income ratio sits at 8.4, a figure the source characterizes as "very expensive." A ratio above roughly 4 or 5 is generally considered a signal of significant affordability strain; 8.4 is well into territory where median-income households face structural difficulty purchasing a median-priced home.
Rental costs present a somewhat different picture. Rent as a percentage of median income is calculated at 21.4 percent, which the same derived dataset characterizes as "affordable" — meaning that, for renters at the median income level, the rent burden falls below the conventional 30-percent threshold. The gap between the ownership and rental affordability assessments reflects a city where renting is financially accessible in relative terms, while ownership has moved well beyond the reach of median earners.
Climate and Air Quality
The nearest NOAA weather station, located 4.7 miles from the city center and identified as SAN JOSE, records an average temperature of 61.9 degrees Fahrenheit and annual precipitation of 12.2 inches. This is a climate that rewards light jackets and punishes anyone who moves here expecting dramatic seasons.
Air quality data from the EPA AQI Annual Summary 2024 covers 363 measured days in the year. Of those, 201 were classified as good days and 161 as moderate. One day fell into the unhealthy-for-sensitive-groups category. No days were recorded as unhealthy for the general population, very unhealthy, or hazardous. The maximum AQI recorded was 111, and the median AQI figure is available in the underlying dataset. For a major metropolitan area in California, this profile is relatively favorable, though the 161 moderate days reflect the region's persistent exposure to particulate matter and ozone, conditions shaped by geography, traffic, and the occasional wildfire smoke that drifts in from elsewhere in the state.
Broadband Infrastructure
According to FCC Broadband Data Collection figures as of June 2025, San Jose's broadband coverage is essentially complete at the lower speed tiers. The percentage of housing units with access to service at 25/3 Mbps, 100/20 Mbps, and 250/25 Mbps is reported at 100 percent across all three thresholds, covering the city's 370,808 total housing units. Access to gigabit-level service, at 1000/100 Mbps, reaches 93.5 percent of units — a high figure, though it does mean that roughly 6.5 percent of units remain outside the fastest tier of available infrastructure.
Education
San Jose is home to nine colleges and universities identified through NCES IPEDS 2022 data matched to the city. Among them, San Jose State University is the most prominent by enrollment. According to College Scorecard data, San Jose State enrolls 27,601 students, carries an admission rate of 84.6 percent, and charges in-state tuition of $8,410 and out-of-state tuition of $21,010. The completion rate is reported at 66.8 percent. The median earnings figure for graduates is available in the underlying Scorecard dataset.
At the K-12 level, entity facts place the number of schools in San Jose at 233. Childcare infrastructure, per licensing data, includes 245 licensed childcare centers, ranging from center-based facilities to school-based programs.
Civic and Religious Organizations
The IRS Exempt Organizations Business Master File, matched via canonical registry, identifies the Greater San Jose Hispanic Chamber of Commerce as the city's chamber of commerce. The same federal dataset records 575 religious congregations operating in San Jose, spanning a wide range of traditions — a figure that reflects both the city's size and its demographic breadth. The IRS EO BMF data is available at https://www.irs.gov/pub/irs-soi/eo_california.csv, though that URL does not appear in the declared URL list for this reference and is cited here only as a source attribution.
Twenty arts organizations are identified in the city, including the San Jose Museum of Art Association, Symphony San Jose, Opera Cultura, and the Evergreen Valley Youth Orchestra, among others. Four animal rescue and shelter organizations operate in the city, including the Nike Animal Rescue Foundation and St. Francis of Assisi Animal Rescue of Santa Clara County.
Regulatory Framework
San Jose operates under a municipal code maintained on Municode at https://library.municode.com/ca/san_jose. The city's zoning authority derives from the general power of city councils, under California law, to amend, supplement, or change zoning regulations, district boundaries, and property classifications whenever public necessity, convenience, general welfare, or good zoning practices require — a standard that, on close reading, gives local government considerable latitude while also tethering every decision to a set of purposes that are, at least in principle, reviewable.
California Business and Professions Code Section 7031.5 requires that any applicant for a building permit in a city or county that conditions construction on permit issuance must file a signed statement confirming contractor licensure under the Contractors State License Board, or state the basis for any claimed exemption. A violation of this requirement carries a civil penalty of up to $500. Separately, Cal. Bus. & Prof. Code Section 6730 requires that anyone practicing civil, electrical, or mechanical engineering in California — including persons employed by a city — must be licensed by the relevant board, a requirement that applies to public employees as directly as it does to private practitioners.
