CSAs, SPAs, and SDs are provided for reference only. Aggregating to these fields does not constitute an official LA County estimate. These boundary labels represent the geography that has the most intersection area with the census tract, as of 2023. ## Source Notes from US Census: To protect respondent confidentiality, data have undergone disclosure avoidance methods which add "statistical noise" - small, random additions or subtractions - to the data so that no one can reliably link the published data to a specific person or household. The Discrete Gaussian Mechanism (DGM) was used, the approved scale parameter for the DGM results in noise values with an absolute value of 3 or less, 95% of the time. Estimates will be suppressed if they fall below 30 for 5-year data and 150 for 1-year data. The Census Bureau encourages data users to aggregate small populations and geographies to improve accuracy and diminish implausible results. Although the American Community Survey (ACS) produces population, demographic and housing unit estimates, the decennial census is the official source of population totals for April 1st of each decennial year. In between censuses, the Census Bureau's Population Estimates Program produces and disseminates the official estimates of the population for the nation, states, counties, cities, and towns and estimates of housing units and the group quarters population for states and counties. Information about the American Community Survey (ACS) can be found on the ACS website (https://www.census.gov/programs-surveys/acs.html). Supporting documentation including code lists, subject definitions, data accuracy, and statistical testing, and a full list of ACS tables and table shells (without estimates) can be found on the Technical Documentation section of the ACS website (https://www.census.gov/programs-surveys/acs/technical-documentation/code-lists.html). Sample size and data quality measures (including coverage rates, allocation rates, and response rates) can be found on the American Community Survey website in the Methodology section (https://www.census.gov/acs/www/methodology/sample_size_and_data_quality/). ACS data generally reflect the geographic boundaries of legal and statistical areas as of January 1 of the estimate year. For more information, see Geography Boundaries by Year (https://www.census.gov/programs-surveys/acs/geography-acs/geography-boundaries-by-year.html). Data are based on a sample and are subject to sampling variability. The degree of uncertainty for an estimate arising from sampling variability is represented through the use of a margin of error. The value shown here is the 90 percent margin of error. The margin of error can be interpreted roughly as providing a 90 percent probability that the interval defined by the estimate minus the margin of error and the estimate plus the margin of error (the lower and upper confidence bounds) contains the true value. In addition to sampling variability, the ACS estimates are subject to nonsampling error (for a discussion of nonsampling variability, see ACS Technical Documentation (https://www.census.gov/programs-surveys/acs/technical-documentation.html)). The effect of nonsampling error is not represented in these tables. Users must consider potential differences in geographic boundaries, questionnaire content or coding, or other methodological issues when comparing ACS data from different years. Statistically significant differences shown in ACS Comparison Profiles, or in data users' own analysis, may be the result of these differences and thus might not necessarily reflect changes to the social, economic, housing, or demographic characteristics being compared. For more information, see Comparing ACS Data (https://www.census.gov/programs-surveys/acs/guidance/comparing-acs-data.html). Estimates of urban and rural populations, housing units, and characteristics reflect boundaries of urban areas defined based on 2020 Census data. As a result, data for urban and rural areas from the ACS do not necessarily reflect the results of ongoing urbanization. #### Disclosure Avoidance Methods All cells in any American Community Survey special tabulation are rounded. The rounding schematic is: * 0 remains 0 * 1-7 rounds to 4 * 8 or greater rounds to nearest multiple of 5 (i.e., 864 rounds to 865, 982 rounds to 980)
