The 2020 U.S. Census counted 31,992 residents in the 2.7-square-mile Del Rey neighborhood—an average of 11,850 people per square mile, about the norm for Los Angeles; in 2010, the U.S. Census counted 31,070 residents; in the 2000 U.S. Census, the population was slightly lower at 28,010. The median age for residents was 38, considered the average for Los Angeles; the percentage of residents aged 20 through 34 was among the county's highest. This was noted in
Federal Housing Administration Redlining plans in the 1930s, which gave the neighborhood a low rating due to the lack of enforced racial segregation. Many residents of Japanese descent were forced to leave as part of the
Internment of Japanese Americans during World War II. A monument has been installed on the corner of Venice and Lincoln Boulevards in nearby Venice, where Japanese residents were ordered to board buses to the internment camps. The median yearly household income in 2020 dollars was $110,065, above average for Los Angeles; while back in 2008, it was $62,259, an average figure for the city. The average household size of 3.1 people was slightly lower than the county, but in 2008, the average household size of 2.5 people was about the same as the city as a whole. Renters occupied about 70.7% of the housing stock (up significantly from 2008 at 55.2%) and house- or apartment-owners held 29.3%. The percentages of
never-married men (44.6%) and divorced women (12.2%) were among the county's highest. In 2000, there were 1,846 veterans, or 8.4%, a high rate for Los Angeles. By 2020, this number was estimated to have dropped to 805 to 1113, or 2.5% to 3.5%. ==Police service==
