The United States Census Bureau is a bureau of the U.S. Department of Commerce. The major functions of the Census Bureau are authorized by Article 2, Section 2 of the United States Constitution, which provides that a census of population shall be taken every 10 years, and by Title 13 and Title 26 of the United States Code of Federal Regulations. The Census Bureau is responsible for numerous statistical programs, including census and surveys of households, governments, manufacturing and industries, and for U.S. foreign trade statistics. The first U.S. census was conducted in 1790 for the purposes of apportioning state representation in the U.S. House of Representatives and for the apportionment of taxes.
Dataset: B10001. Grandchildren Under 18 Years Living with a Grandparent Householder by Age of Grandchild from the American Community Survey Summary File: 5-Year Estimates, 2016-2020 DatabasePresents an estimate of the numbers of children under age 18 in the United States living with a grandparent householder. Estimates are reported for specified geographic areas. A household includes all the people who occupy a housing unit. (People not living in households are classified as living in group quarters.) A housing unit is a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied (or if vacant, is intended for occupancy) as separate living quarters. One person in each household is designated as the householder. In most cases, this is the person, or one of the people, in whose name the home is owned, being bought, or rented and who is listed on line one of the survey questionnaire.
The American Community Survey (ACS) conducted by the US Census Bureau provides estimates of the characteristics of the population over a specific time period. The ACS collects data from the 50 states, Washington, DC, and Puerto Rico, where it is called the Puerto Rico Community Survey. It is a continuous survey, in which each month a sample of housing unit addresses receives a questionnaire, with approximately 3.5 million addresses surveyed each year. Each year the survey produces data pooled to produce 1-year, 3-year, and 5-year estimates for geographic areas in the US and Puerto Rico, ranging from neighborhoods to congressional districts to the entire nation. Data for each release of the 5-year estimates were collected over a 5-year period ending December 31 of the reference year (eg, data in the 2020 5-year estimates were collected January 1, 2016 - December 31, 2020). The statistics reported represent the characteristics of the population for the entire period vs a specific year within that period. The 5-year estimates are published for areas with populations of all sizes and are the most reliable and precise of the ACS period estimates as well as the most comprehensive, albeit the least current. (The 1-year estimates provide data on areas with populations of 65,000+ and 20,000+, respectively.) The ACS estimates provide information about the social and economic needs of communities and are used to help determine how billions in federal and state funds are distributed each year. It is conducted under the authority of Title 13, United States Code, Sections 141 and 193.
Data Planet publishes the ACS base tables designated with a “B,” which provide the most detailed estimates on all topics “B,” which provide the most detailed estimates on all topics and for all geographies. (The Census Bureau also publishes "C" tables released as Comparison Profiles, “D” tables released as Data Profiles, and “S,” or Summary, tables.) Certain of the tables are repeated by nine race and/or Hispanic or Latino groups, identified by the Census Bureau with a suffix (A-I) that pertains to a specific race/ethnic group. For detailed information on code lists, subject definitions, data accuracy, statistical testing, and sampling methodology and error, please see the technical documentation. Note that statistics presented as dollars refer to inflation-adjusted dollars of the survey release year. Industry and occupation classifications have been updated to align with the 2017 North American Industrial Classification System and 2018 Standard Occupational Classification (SOC) codes, respectively. Data Planet published Census-provided margin of error (MOE) values for estimates and should be interpreted as a +/-[value]. These values reflect the variation in the estimates over all possible samples that could have been selected from the population using the same sampling methodology and should be taken into account in analyses of the data. For more detail on MOEs, please see https://www2.census.gov/programs-surveys/acs/tech_docs/accuracy/MultiyearACSAccuracyofData2020.pdf .
