1. CENSUS2010POP: This term refers to the population count recorded during the
decennial census conducted in the year 2010. The "CENSUS2010POP" value
represents the actual population count as of April 1, 2010, based on the responses
received from households and individuals who participated in the 2010 Census.
2. ESTIMATESBASE2010: "ESTIMATESBASE2010" is the population estimate base for
subsequent years. It serves as the starting point for population estimates and
projections for the years following the 2010 Census. This value is calculated based on
the 2010 census population count and serves as a benchmark for estimating how the
population changed over time.
3. POPESTIMATE2010: "POPESTIMATE2010" represents the estimated population of a
given geographic area (e.g., a state, county, or city) as of July 1, 2010. It is an estimate
that takes into account population changes that occurred after the 2010 Census. The
estimate typically considers factors such as births, deaths, international migration,
and domestic migration.
In summary, "CENSUS2010POP" is the actual population count from the 2010 Census,
"ESTIMATESBASE2010" is the population estimate base derived from the 2010 Census count,
and "POPESTIMATE2010" is the estimated population for the year 2010 based on
demographic trends and changes that occurred between April 1, 2010, and July 1, 2010.
Population Base + Births – Deaths + Migration = Population Estimate
4. NPOPCHG: Net population change. It represents the total population change due to
various factors such as births, deaths, and migration over this time frame.
NPOPCHG_2010 = POPESTIMATE2010 - ESTIMATESBASE2010
NPOPCHG_2011 = POPESTIMATE2011 - POPESTIMATE2010
etc.
5. BIRTHS: The number of live births.
6. DEATHS: The number of deaths that occurred within a specific geographic area
during a given time period.
7. NATURALINC: Natural population increase. It is calculated as the difference between
the number of births and deaths within a specific time period. It reflects the
population change due to natural processes.
NATURALINC = BIRTH+ DEATH
8. INTERNATIONALMIG: refers to the number of international migrants (people moving
into the area from other countries). It represents the net international migration,
which is the difference between the number of people who immigrated to the area
from other countries and the number of people who emigrated from the area to
other countries.
9. DOMESTICMIG: represents the number of domestic migrants (people moving within
the country). It indicates the net domestic migration, which is the difference between
the number of people who moved into the area from other parts of the country and
the number of people who moved out of the area to other parts of the country.
10. NETMIG: is net migration and is calculated as the difference between international
migration and domestic migration within a specific time period. It reflects the overall
migration flow.
NETMIG = INTERNATIONALMIG + DOMESTICMIG
11. RESIDUAL: Represents the residual component of population estimates. It's the
unexplained difference between demographic analysis estimates and the official
census count. It can capture discrepancies in data or analysis. The residual can be
positive or negative, and it is used as an indicator of the accuracy of the population
estimates. A positive residual indicates that the population estimates were lower
than the actual count, while a negative residual suggests that the estimates were
higher.
12. GQESTIMATESBASE2010: refers to the estimates base for group quarters (GQ)
population for the year 2010. Group quarters are institutional or communal living
arrangements where people live and eat in a group, rather than in a private
household. This category includes places like correctional facilities, nursing homes,
college dormitories, and military barracks. The "GQESTIMATESBASE2010" provides a
starting point for estimating the population living in group quarters for the year 2010.
It is used to calculate estimates for the population in group quarters, which can be
different from the population living in households.
13. GQESTIMATES: Population estimates for people residing in group quarters.
14. RBIRTH: is the birth rate. It represents the number of births per 1,000 people in the
population for a given time period. It's a measure of fertility.
Birth Rate = (Number of Births / Total Population) × 1,000
15. RDEATH: is the death rate. It represents the number of deaths per 1,000 people in
the population for a given time period. It's a measure of mortality.
Death Rate = (Number of Deaths / Total Population) × 1,000
16. RNATURALINC: is the natural increase rate. It represents the difference between the
birth rate and the death rate, expressed per 1,000 people in the population for a
given time period.
RNATURALINC = RBIRTH + RDEATH
17. RINTERNATIONALMIG: is the international migration rate. It represents the number
of international migrants per 1,000 people in the population for a given time period.
International Migration Rate = (Number of International Migrants / Total Population)
× 1,000
18. RDOMESTICMIG: is the domestic migration rate. It represents the number of
domestic migrants per 1,000 people in the population for a given time period.
Domestic Migration Rate = (Number of Domestic Migrants / Total Population) ×
1,000
19. RNETMIG: is the net migration rate. It represents the difference between the
international migration rate and the domestic migration rate, expressed per 1,000
people in the population for a given time period. It reflects overall migration.
RNETMIG = RINTERNATIONALMIG + RDOMESTICMIG
