Report or project title: Projected Population of the State of North Carolina and North Carolina Counties for July 1, 2020 through July 1, 2050 Publisher and year of publication: North Carolina Office of State Budget & Management, Demographic & Economic Analysis Section, 2021 Brief description and notes: From the Technical Documentation: "Beginning in March 2020, North Carolina’s population experienced extensive
social and economic disruptions due to the global COVID-19 pandemic. Like the global pandemic of over 100 years ago, this pandemic has affected population
change over the past year and will continue to do so until more of the population is vaccinated and the pandemic is under control.
"These projections are prepared using the same methods and assumptions used for our annual projections – mainly that most recent trends in
population change and in the components of population change (births, deaths, and net migration) continue into the future. However, in order to
account for the impacts of COVID-19, these assumptions were modified for the short term and assume additional deaths, fewer births, and slower
net migration due to the pandemic and concomitant economic fallout. As a result, these population projections predict 55,000 fewer people by 2023
than had the pandemic not occurred and 71,000 fewer people by 2050." Population estimates for 2000 to 2019 are included with the projections data. Materials:

The REMI model provides information for all 17 counties by 23 major economic sectors. It looks at the dynamic economic and demographic
relationships between the 17 counties and the United States as a total. The 20 year projections are produced annually and will change
as more historical data becomes available or is revised. Because REMI looks at the relationship between changes in the economy and in
population, it is a useful tool for looking at how changes in either the structure of the population or the economy can impact the other.
For much of its history, Nevada’s growth had been driven by migration through job creation in the accommodations and food services sector
(the category which covers hotel casinos)." The report covers Nevada, its counties, and the Reno-Carson City-Fernley Combined Statistical Area. Materials:

Report or project title: Provisional Projections of the Population of States, by Age and Sex: 1980 to 2000 Publisher and year of publication: U.S. Bureau of the Census, 1983 Brief description and notes: The abstract provided on the associated web page: "This report presents projections of the resident
population of each State by 5-year age groups and sex for July 1, 1990 and 2000. These projections represent the first series of State
population projections released by the Census Bureau that are based on the 1980 census results and that are consistent with the middle series
of national population projections published as Current Population Reports, Series P-25, No. 922. This set of projections is provisional in
that it was developed with a cohort-component projections model employing residual measures of migration. The projections presented here are
not forecasts of each State's future growth patterns. They present the results of continuing the migration patterns by age and sex estimated
for the 1970-80 decade. When the full migration data are tabulated from the 1980 census question on residence 5 years ago, we will prepare a
revised set of State population projections using more refined measures of migration." The report includes analysis of previous projections,
and comparison of 1980 projected populations to 1980 Census populations. Materials:

Report or project title: Illustrative Projections of State Populations by Age, Race, and Sex, 1975-2000 Publisher and year of publication: U.S. Bureau of the Census, 1979 Brief description and notes: From the report's introduction: "This report presents illustrative projections of the resident population of
the fifty States and the District of Columbia, classified by age, race, and sex for the years 1980, 1985, 1990, 1995, and 2000, as well as data on
components of population change. These projections are based on revised gross migration data for the 1965-70 period and postcensal estimates of
net migration through 1975. The current set of State population projections was prepared using the cohort component method of demographic analysis.
This method permits the separate projection of the three components of population change--fertility, mortality, and net migration--for each age,
race, and sex group. The projections presented in this report contain a further refinement in methodology in that in-migration and out-migration
are treated separately, and civilian noncollege, military, and college populations are handled individually. The military and college populations
exhibit unique patterns of migration and warrant separate treatment. "This report present two main series of State population projections along
with a purely hypothetical series for comparison purposes. The series have common assumptions concerning projected fertility and mortality derived
from the fertility and mortality assumptions of Series II of the current set of national population projections. The major differences in population
growth between States is due to the third component--migration. Given the unpredictability of this component at the State level, several different
assumptions about net migration have been relied upon to illustrate the impact of differing levels of migration on population growth."

Report or project title: Projections of the Population of Metropolitan Areas: 1975 Publisher and year of publication: U.S. Bureau of the Census, 1969 Brief description and notes: Excerpts from the report's page 1: "This report presents population projections to
1975 for metropolitan areas as defined in the 1960 Census. These metropolitan area projections, together with those for the nonmetropolitan
portion of each State, are consistent with the State projections previously published in report No. 375 of this series, and with the national
projections in report No. 381. The projections also take into account estimates of metropolitan and non metropolitan population change to 1965
and thus are consistent with estimates presented in report No. 371." "The projections were developed by a cohort component method whereby births,
deaths, and gross out- and in-migration were projected separately. Two main series are presented, differing according to the national fertility
assumptions employed. For analytical purposes, projections assuming no net inter-area migration are also shown. The alternative fertility assumptions
correspond to those developed as Series B (medium high) and Series D (low) for the national population projections. Differences of SEA fertility
rates from national rates are taken into account. A single set of projected national mortality rates by age and sex was used for all areas." Materials:

Report or project title: Preliminary Projections of California Areas and Counties to 1985 Publisher and year of publication: California Department of Finance, 1967 Brief description and notes: From page 1 of the report: "The assumptions underlying any set of population projections can be
divided into the general and the specific. The general assumptions state that the
basic conditions of the world will not deviate sufficiently from those expected to affect the population significantly.
Neither natural calamity nor fundamental institutional changes nor changes in the conditions of war and peace are considered.
Specific assumptions embrace deaths, births and migration."
The projections include total population projections by county for 1970, 1975, 1980, and 1985, along with total population estimates for 1960
and 1965. The model framework is unclear, but includes use of mortality, migration, and age specific birth rates. Materials:

States for 1970 to 1985, taking into account national population projections and estimates of State changes in population that have become
available since the last State projections were prepared. Thus, they are consistent with the recent national population projections published
earlier this year in Current Population Reports, Series P-25, No. 359, and with estimates of State population, by age, published in Series P-25,
No. 354. "Four alternative series of projections are given here, based on reasonable alternative assumptions concerning future national fertility
and interstate migration. (Only one assumption concerning future mortality is used.) For analytical purposes, a set of projections assuming no net
migration is also shown. The projections are not intended as predictions, but rather as indications of the population distributions which would
develop on the basis of the assumptions regarding births, deaths, and interstate migration which were selected."

population projections shown here. The first method, which may be described as a 'component' method, involves preparation of separate
projections of each of the components of population change, i.e., births, deaths, and net migration. The other procedure is the one
usually referred to as the 'ratio' method. This method involves extrapolating the ratio of the population of a State to that of the
United States and applying these ratios to projections of the population of the United States." Data provided include projected population

geographic division, and State, for 1955 and 1960, taking into account the 1950 Census totals for these areas. The projections are designed
to represent the civilian population of each area plus members of the armed forces who resided in the area at the
time of their entry into the armed forces. This type of population cannot be enumerated easily or reliably in a census, but is the type for
which the most realistic assumptions can be made as to future change and for which the most useful projections can be provided. Users of
these projections can then develop projections of the resident population of each area by making whatever assumptions as to future military
changes they consider appropriate." "A 'ratio' method was selected after consideration had been given, from the point of view of validity
and cost, to several possible methods of projecting State populations." Materials:

This State and Local Population Projections Database brings together population projection information and materials
from different sources through survey response and file sharing. The database can be used by population projection
developers and researchers for the study and analysis of population projection methods, and associated uncertainty.
Historical as well as current population projections are included in the database, it includes a mix of sources and
methods, and it can be added to over time. The design of the database is United States-focused, but projections from
other countries can be added too. The database is for independent analysis of population projections, and is not
authoritative for any of the included works. Database items are hosted primarily on Google Drive, and backed up
periodically, and the webpage and supporting content for the database are hosted on GitHub.
