San Diego is the eighth-most populous city in the United States and second-most populous in California with over 1.4 million residents, located on the Pacific coast of Southern California adjacent to the Mexico-United States border. Known as the Birthplace of California, San Diego was first visited by Europeans in 1542 when Spanish explorer Juan Rodríguez Cabrillo claimed the area for Spain, with the Presidio and Mission San Diego de Alcalá establishing the first European settlement in California in 1769. The city's economy is driven by military and defense activities, tourism, international trade, research, and manufacturing, and it hosts major universities including UC San Diego and San Diego State University. San Diego is renowned for its mild Mediterranean climate, extensive beaches and parks, strong naval presence, and emergence as a center for wireless, electronics, healthcare, and biotechnology development. The city anchors the San Diego-Tijuana transborder region home to an estimated five million people, with the San Ysidro Port of Entry serving as the world's fourth-busiest international land border crossing and San Diego International Airport operating as the nation's busiest single-runway airport. Chula Vista is California's 15th-most populous city and the second-largest in the San Diego metropolitan area, with 275,487 residents according to the 2020 census, located 7.5 miles between San Diego and Tijuana in the South Bay region. Originally inhabited by the Kumeyaay people for hundreds of years, the area was claimed by Spanish conquistador Juan Rodríguez Cabrillo in 1542 and later became part of Mexican ranchos before U.S. acquisition in 1848 and California statehood in 1850. Founded in the early 19th century and incorporated in October 1911, Chula Vista has experienced rapid recent population growth, expanding from 243,916 residents in 2010 to 275,487 by 2020. The city is home to major attractions including the Chula Vista Elite Athlete Training Center, Sesame Place San Diego, the North Island Credit Union Amphitheatre, and the Living Coast Discovery Center. Named from Spanish meaning "beautiful view," Chula Vista's scenic location between San Diego Bay and coastal mountain foothills defines its geographic and cultural character. El Cajon, located 17 miles east of downtown San Diego in San Diego County, California, had a population of 106,215 as of the 2020 census and takes its nickname "the Box" from the box-like shape of its surrounding valley. The city's name, Spanish for "the drawer," was first recorded on September 10, 1821, as an alternative name for Rancho Santa Mónica and was formally expanded to "El Cajon" in 1905 at the insistence of California banker and historian Zoeth Skinner Eldredge. During Spanish rule (1769-1821), mission padres used the El Cajon Valley's foothills and watershed to support mission cattle herds, and in 1845, California Governor Pio Pico granted the 11-square-league Rancho Santa Monica to Dona Maria Antonio Estudillo to repay a government obligation. After the Mexican-American War, the land grant was confirmed by the U.S. Supreme Court and patented in 1876, with Los Angeles developer Isaac Lankershim purchasing the bulk of the holdings in 1868 and employing manager Amaziah Lord Knox to establish a hotel in 1876 serving travelers between San Diego and Julian, where gold had been discovered in 1869. El Cajon developed around Knox's Corners, which became a stop for travelers and later a significant regional center in San Diego County.
