![]() We will update and add any new exchange information as we come across them (or you tell us about them). Information collected from personal recollections contributed may be imperfect. ![]() The list is not exhaustive nor do we guarantee absolute accuracy. Below is a list of exchange names and numbers for Los Angeles County gleaned from the Telephone EXchange Name Project, compiled by Robert Crowe, and from recollections offered by visitors to the Los Angeles Almanac. These old exchange names are remembered in Glenn Miller’s song PEnnsylvania 6-5000 and Elizabeth Taylor’s movie BUtterfield-8. In 1958, due to increased consumer demand for individual telephone numbers, the telephone company began phasing out old exchange names for all numeric telephone numbers or "All Number Calling" (pretty much gone by 1963).

The 2010-2020 postcensal estimates are known to underestimate the population by about 1% nationally. Use caution when interpreting population changes that use different “postcensal” version estimates. We will update this experience, including the 2010-2019 estimates, when the Bureau releases county-level 2010–2020 intercensal estimates by age, sex, race, and ethnicity. The most recent county-level data available by age, race, sex, and ethnicity are the Vintage 2020 Population Estimates () for 2010 to 2019 and the Vintage 2021 Population Estimates () for 20. These provisional estimates are “postcensal estimates,” and the final estimates are “intercensal estimates.” USAFacts used the final intercensal estimates for 1970 through 2009 and the provisional postcensal estimates for 2010 and after. Every decade, the Bureau reconciles these estimates and releases final data. The Census Bureau releases annual provisional population estimates based on the previous decennial census and other data on births, deaths, and migration/immigration. ![]() The “less than 1” and “1 to 4” groups for the 19 censuses were combined to create a consistent “0 to 4” group across all available data. Comparison pages include footnotes explaining that pre-2000 and post-2000 data comparisons will result in lower values for the separate race categories in proportion to the expected “two or more race” population.įor population by age, USAFacts grouped people ages 0–4 in different ways depending on the census. This category can’t be compared prior to 2000. These were the only categories included before 1990 for the available data.Īny comparison with the 1990 census to newer data will include the “white,” “Black,” and two categories added that year: “American Indian/Alaska Native” and “Asian or Pacific Islander.”ĭata from 2000 onward will also include the “Two or more race” category. To provide the most detail across all available data, USAFacts combined the census data on race and ethnicity into three groupings.Īny comparison of data from before 1990 only includes the “white,” “Black,” and “Other” race/ethnicity categories. But how the Census Bureau reported and grouped those populations changed over time. The Census Bureau’s Population Estimates Program data by county includes details like counts by age, race, or ethnicity and goes back for decades.
