1: Census / population projections Flashcards
Metropolitan Statistical Area (MSA)
A MSA includes at least one city with 50,000 or more inhabitants, or an urbanized area (of at least 50,000 inhabitants), and a total metropolitan population of at least 100,000.
Consolidated MSA
A Consolidated MSA is made up of several PMSA’s. An example is the Dallas-Fort Worth Consolidated Metropolitan Area. Dallas and Fort Worth are each primary metropolitan statistical areas.
Core Based Statistical Area (CBSA)
A Core Based Statistical Area is defined by the US Office and Budget to provide data description for areas where there is a core area with at least 10,000 people that when combined with other adjacent communities is socially and economically integrated.
Census Tract
Typically has a population between 2,000 and 8,000 people.
Its the smallest area where all information is released.
Census Block
The smallest level at which the Census data is collected. There are typically
400 housing units per block.
Census Block Group
A group of Census Blocks.
They generally contain 600-3,000 people, and are used to present data and control block numbering.
Cohort Survival Method
Uses the current population plus natural increase (more births, fewer deaths) and net migration (more in-migration, less out-migration) to calculate a future population.
Deaths, births, migration, and fertility rates are components of this population projection method.
THE MOST accurate population projection, requires tons of data. Detailed, very accurate method to make short term population projections that can handle many variables.
Shortest time interval for which estimate can be made is the length of time it takes for all members of an age cohort to age (ex 10-14). If data is available for each age (year) the method can be used to project the population year by year.
Shift-Share
(population projection)
(analysis)
The population projection technique that allocates a projected population expansion to subregional areas is called.
DIFFERENT THAN
A shift-share analysis, determines what portions of regional economic growth or decline can be attributed to national, economic industry, and regional factors. The analysis helps identify industries where a regional economy has competitive advantages over the larger economy. To conduct a shift-share analysis one must know the industry employment for the region and the nation.
2010 Census fastest growing region
The South by 14.3%
Power Towns
Include anchor department stores with a lifestyle center
Natural Increase
Difference between number of children born and number of people who die during one time interval (basically part of the cohort-survival method)
Ratio (step-down) method
ratio between population of a city & a county at a known point in time such as the census to project future populations
Tribal Designated Statistical Area (TDSA)
TDSAs are statistical geographic entities identified and delineated for the Census Bureau by federally recognized American Indian tribes that do not currently have an American Indian reservation and/or off-reservation trust land.
A TDSA is intended to encompass a compact and contiguous area that contains a concentration of individuals who identify with the delineating federally recognized American Indian tribe. TDSAs are also intended to be comparable to American Indian reservations within the same state or region and provide a means for reporting statistical data for the area.
Threshold population
A term that is under a number of government programs to determine program eligibility.
Urbanized area
The Census Bureau defines an urbanized area wherever it finds an urban nucleus of 50,000 or more people.
Must have core with population density of 1000 people per square mile - may contain adjoining territory with at least 500 people per square mile.
Urban cluster
Urban clusters have at least 2,500 but less than 50,000 persons and a population density of 1,000 persons per square mile. This delineation of built-up territory around small towns and cities is new for the 2000 Census.
Micropolitan Statistical Area
A population of more than 10,000 people and less than 50,000 people. This includes a central county and adjacent counties that have a high degree of social and economic integration as measured by commuting.
Census Designated Places
(CDP)
The equivalent of an incorporated place for data purposes. This is for settled concentrations of population that are not incorporated.
American Community Survey
(ACS)
This survey, which replaces the long form in the decennial Census, takes a sample of the population and projects the findings to the population as a whole.
Reaches 2.5% of the nation’s population yearly.
Population growth calculation (doubling)
Rule of 70:
70 / Rate of growth (as decimal)
