This dataset is published by the Research & Analytics Group at the Atlanta Regional Commission to show population change by utilizing the 2020 redistricting data and comparable data for 2010, 2000, and 1990 across multiple geographies for the State of Georgia. For a deep dive into the data model including every specific metric, see the Data Manifest. The manifest details ARC-defined naming conventions, names/descriptions and topics where applicable, summary levels; source tables; notes and so forth for all metrics.

It should be noted:The 2020 redistricting release is not as detailed in terms of data compared to ACS estimates; data include total population, population by race and ethnicity, and "voting age" population (i.e., adults) by race and ethnicity, adults are subtracted from the total population to show children (ages 0-17); total number of housing units, occupied housing units, and vacant housing units. Percent and change measures are calculated over four different Censuses.These data are expressed in terms of 2020 geographies such as the new 2020 Census tracts. This means that that historical data for geographies like cities have been estimated to the 2020 boundaries. For example, the city of Atlanta, which has made multiple annexations since 1990, has a higher estimated 1990 population of 400,452 (2020 boundaries) than the 394,017 reported in the 1990 Census (1990 boundaries).Due to changes in block geographies and annexations, 2010 population totals for custom geographies such as City of Atlanta NSAs may differ slightly from the numbers we have published in the past.The procedure to re-estimate historical data to 2020 blocks often results in fractional population (e.g., 1.25 instead of 1 or 2). Counts have been rounded to the nearest whole, but to be more precise, all aggregation, percent, and change measures were performed pre-rounding. Some change measures may appear curious as a result. For example, 100.4 - 20.8 = 79.6 which rounds to 80. But if rounded first, 100.4 rounds down to 100, 20.8 rounds up to 21; 100 - 21 = 79.Asian and Pacific Islander categories are combined to maximize compatibility with the 1990 release, which reported the two groups as a single category. Caution should be exercised with 1990 race data because the Census Bureau changed to the current system (which allows people to identify as biracial or multiracial) starting only in 2000.The "other" race category includes American Indian and Alaska Natives, people identifying with "some other race" and (for 2000 forward), people who identify as biracial or multiracial.For more information regarding Decennial Census source data, visit 2020 Census website

The Metropolitan Planning Area (MPA) boundary is the line that includes the entire existing urbanized area defined by the United States Census, plus the areas expected to urbanize in the next 20 years. These areas are the basis for long-range and short-range transportation plans required by Federal law.After each Census, Federal rules require that ARC and local governments redraw the boundary. Being included in the MPA means those local governments can apply for federal funding through the TIP process and become eligible for funding under the Livable Centers Initiative, the comprehensive transportation plan, and other ARC projects. Following the 2020 Census, the Census Bureau designated a revised Atlanta Urbanized Area(UA) based on 2020 Census data. The Atlanta UA includes all or part of 20 counties, down from the 23 counties designated following the 2010 Census. These 20 include Barrow, Bartow, Cherokee, Clayton, Cobb, Coweta, Dawson, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Hall, Henry, Newton, Paulding, Rockdale, Spalding, and Walton counties.The Census applied new, stricter criteria in determining whether a census tract was urban or rural. In some places, this has meant that the Atlanta UA appears to have gotten smaller. For this reason, Pike County is no longer included in either the Atlanta Urbanized Area or the new MPA boundary. The Atlanta UA also no longer extends into Carroll County, though the new MPA boundary will include part of Carroll County as detailed below. The parts of Jackson County previously included in the Atlanta UA are now classified with the Gainesville UA. Adjacent to the Atlanta UA are the Cartersville and Gainesville UAs. These areas are represented by their own metropolitan planning organizations (MPOs). By previous formalagreement, ARC has assigned transportation planning responsibilities for the portion of the Atlanta UA in Bartow County to the Cartersville-Bartow Metropolitan Planning Organization (CBMPO).By similar previous formal agreement, ARC has assigned transportation planning responsibilities for the portions of the Atlanta UA in Hall and Jackson counties to the Gainesville-Hall Metropolitan Planning Organization (GHMPO), while GHMPO has assigned transportation planning responsibilities for the portions of the Gainesville UA in Forsyth and Gwinnett counties to ARC. These agreements will be updated to reflect new geographies andnecessary agreements following the 2020 Census.Data from the 2020 Census identified a new Winder Urban Area existing in Barrow,Gwinnett, and Walton counties. With a population of 50,189, the Winder UA exceeds the threshold of 50,000 established by Federal law to be designated as its own MPO. Conversations continue between ARC, the State, the City of Winder, and Barrow County about whether the City and County will form their own MPO; Federal law requires agreementbetween the two bodies. Until and unless Winder and Barrow County elect to form an MPO, they shall remain part of ARC. Should a Winder MPO be created, the new agreement between ARC and GHMPO will also need to include the new Winder MPO and divide transportation planning responsibilities in Barrow, Gwinnett, Hall, and Walton counties between the three agencies. ARC has developed the attached revised Metropolitan Planning Area through discussions with planning partners.• Like before, the new MPA boundary continues to contain the ARC’s 11-county region (Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Forsyth, Fulton, Gwinnett, Henry, and Rockdale) in its entirety, as well as the entirety of Coweta and Paulding counties.• Newton County is now included in the new MPA boundary in its entirety to account for significant growth along Interstate 20 in the Covington and Stanton Springs areas.• Barrow County is also now included in the new MPA boundary in its entirety until and unless the City of Winder and Barrow County form their own MPO.• While the Atlanta UA was reduced in Spalding County, and a separate Griffin UA identified that does not meet the minimum threshold to form its own MPO, the new MPA boundary expands to include all of Spalding County to account for expected growth along Interstate 75, US 19-41, and State Route 16.• In Dawson County, the new MPA boundary accounts for population growth along Lake Lanier.• In Walton County, the new MPA boundary includes areas that the Census has designated as urban, as well as the cities of Monroe and Social Circle.• Carroll County is no longer considered part of the Atlanta Urbanized Area. The county contains two separate Urbanized Areas, Carrollton and Villa Rica, neither of which is large enough to form its own MPO. Because the City of Villa Rica is geographically divided between Carroll and Douglas counties, the City has opted to remain entirely within ARC. Accordingly, the new MPA boundary includes the portion of Villa Rica in Carroll County.

Abstract (en): This study was a joint project of ten major United States cities participating in the Urban Observatory Program: Atlanta, Albuquerque, Baltimore, Boston, Denver, Kansas City, Kansas, Kansas City, Missouri, Milwaukee, Nashville, and San Diego. The survey focused on citizens' perceptions of the problems of urban life. Citizens' attitudes toward local government services and their opinions about local problems in the areas of schooling, housing, public transportation, controlled drugs, law and order, and taxes were assessed in all ten cities. Information on the socioeconomic status of the respondents, and on household composition was also elicited. Demographic data include sex, age, marital status, race, ethnicity, birthplace, level of education, and family income. Each city may be analyzed separately or may be treated as an integral part of the comparative study. ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection: Standardized missing values.; Checked for undocumented or out-of-range codes.. Adult populations of Atlanta, Albuquerque, Baltimore, Boston, Denver, Kansas City, Kansas, Kansas City, Missouri, Milwaukee, Nashville, and San Diego. An independent sample was drawn from each of the cities included in the study. The samples were designed to represent a cross-section of all households within the politically-defined limits of each central city. They were drawn from the cities' directories and corrections were made with block supplements. Each household in a given city had an equal probability for selection. Within selected households, one adult was designated as respondent and no substitutions were permitted. The samples are not representative of the total United States population living in Standard Metropolitan Statistical Areas.
