Union City, California

Union City is a city in Alameda County, California, in the San Francisco Bay Area of the United States. It lies about 19 miles south of Oakland, 30 miles from San Francisco and 20 miles north of San Jose, and with its neighbours Fremont and Newark it is known as one of the Tri-Cities. Hayward bounds it on the north. The 2020 census counted 70,143 residents, up from 69,628 in 2010. The city has a total area of about 19 square miles, all of it land with no bay frontage, and much of its water comes from the Niles Cone aquifer. The first non-native community here was founded in 1850 by John and William Horner, who named it for their steamship, The Union. Alvarado and Decoto, two older communities, voted to combine and incorporated together as Union City in January 1959, and the city marked its fiftieth anniversary in 2009. It has an industrial past as a railroad and steel town and was the site of the first successful sugar beet mill in the United States.
