In the early 20th century, the East Hollywood area was a farming village that also encompassed some of what is now Los Feliz.

[citation needed] In 1916 steel magnate Andrew Carnegie donated the money to construct the Cahuenga Branch of the Los Angeles Public Library on Santa Monica Boulevard.

The University of California Southern Branch, needing more space, moved west at the end of the 1920s to a ranch called Westwood and became UCLA.

[citation needed] In the summer of 1999, three Metro Red Line subway stations opened, connecting East Hollywood more efficiently to the rest of the city.

[citation needed] The 2000 U.S. census counted 73,967 residents in the 2.38-square-mile East Hollywood neighborhood—or 31,095 people per square mile, the third-highest population density in the city.

[3] The neighborhood was "moderately diverse" ethnically within Los Angeles, the statistics being Latino people of any race, 60.4%; Asians, 15.5%; non-Hispanic Whites, 17.5%; blacks, 2.4%; and others, 4.1%.

El Salvador (21.2%) and Mexico (20.1%) were the most common places of birth for the 66.5% of the residents who were born abroad—which was a high percentage compared to Los Angeles as a whole.

According to the Times, East Hollywood includes the smaller neighborhoods of Thai Town, Little Armenia and Melrose Hill.
