Arleta is bordered by the Los Angeles districts of Mission Hills and North Hills on the north, Sun Valley on the east, Pacoima on the northeast, and Panorama City on the west. It lies within the 6th City Council district.
The boundaries of Arleta are roughly Paxton Avenue on the northwest, Laurel Canyon Boulevard on the northeast, Tonopah Avenue on the southeast, and Woodman Avenue on the southwest, making the square area about four miles (6.4 km), according to Google Earth.
The area of Arleta was a relatively undeveloped portion in the west of the community of Pacoima. This area remained semirural up to World War II when manufacturers expanded their operations into the valley and created more jobs. In order to accommodate factory workers, residential development increased in the area. 
Most of Pacoima developed into a multiethnic neighborhood with a significant population of African-American and Latino residents, whereas the western portion remained primarily white. The 5 Freeway was built in the early 1960s and created a physical barrier between east and west Pacoima, and in the same period, residents in the western half led a petition and successfully broke from the neighborhood to form Arleta; the new neighborhood was officially recognized in 1968.
As industrial jobs began to decrease in the valley, many residents left the area in the 1980's; following this, Arleta became much more diverse and as of the 2010s, it shares the majority Latino demographics of Pacoima.
The 2000 U.S. census counted 31,068 residents in the 3.10 square miles (8.0 km2) Arleta neighborhood—or 10,034 people per square mile, an average population density for the city. In 2008, the city estimated that the population had increased to 32,622. In 2000 the median age for residents was 29, about average for city neighborhoods. The percentage of residents aged 11 to 18 was among the county's highest.
The neighborhood was considered "moderately diverse" ethnically within Los Angeles, with a relatively high percentage of Latinos. The breakdown was Latinos, 71.7%; Asians, 11.0%; whites, 13.2%; blacks, 2.2%; and others, 1.9%. Mexico (55.3%) and El Salvador (11.2%) were the most common places of birth for the 46% of the residents who were born abroad—which was a high percentage for Los Angeles.
The median yearly household income in 2008 dollars was $65,649, considered average for the city. Renters occupied 19.6% of the housing stock, and house- or apartment-owners held 80.4%. The average household size of 4.0 people was considered high for Los Angeles. The 11.5% of families headed by single parents was considered about average for city neighborhoods.
