The following is a list of sources used in the creation of encyclopedia articles on various geographic topics and locations, such as
cities,
counties,
states, and
countries. These sources are cited within the thousands of articles in Wikipedia.
International references
The
CIA World Factbook,[1] which contains tables of miscellaneous facts about the countries of the world.
The U.S. Department of State website, which contains a variety of facts and statistics about countries of the world.[2]
On this wiki, we will use the Third Population Census of Bangladesh, which was conducted by Bangladesh Bureau of Statistics on 12, 13, 14 and 15 March, 1991 because the latest census data is not released online yet.
Bangladesh started census taking in 1872, and then the second census was undertaken in 1881. After that, First Census (Pro Independent) was held 1974 because of the liberation war, and second census was held 1981 and then every 10 years.
Central Statistics Office Ireland: Data from the 2002 Census, including cities, villages, towns, counties and
Gaeltacht regions.[15]
Italy
ISTAT, the official census arm of the Italian government, provides detailed demographic breakdowns and aggregate population figures for all the
comuni, provinces and regions: currently the latest census year available is 2003.[16]
Guida ai Comuni d' Italia (Metropolis), an unofficial site that reproduces ISTAT data from other census years, and other information from official sources (surface areas of the comuni, names of frazioni and località, etc.)[17]
The
United States Census Bureau's
2000 Census gazetteer. This was the primary source for the latitude and longitude values for about 23,500 U.S. cities. The data are indexed by state, county, and place
FIPS codes.[19]
GR2
The
United States Census Bureau's
2000 Census data. Much of the geographic and demographic information for the U.S. states, counties, and cities came from the data on the site. The data is not totally accurate due to various polling errors, but it is a very good estimate. See the Bureau's website for more information. The data were used for the following topics: geographic areas (total, land, and water), population and housing unit densities, demographic spreads across race, age, sex, and income. The data are indexed by state, county, and place FIPS codes. See also
Race (United States Census) for a list of the definition of race according to the U.S. Census Bureau.[20]
GR3
The
Geographic Names Information System developed by the
United States Geological Survey. The data contain information on a wide range of geographic features such as populated places, rivers, mountains, etc. The data provided include geographic coordinates, elevation, population (if applicable), and the FIPS codes for the state and county containing the feature (but not the feature itself).[21] Note that elevations might be interpolated, locations of non-point features may be either approximate centres or mouths, and locations of cities may be arbitrary choices of a feature within the city. Buildings, post offices, and several other feature classes were added during phase 2, but were removed in 2017 when they were considered in retrospect too burdensome to maintain. Some data views may have been based upon topical subsets, such as the National Map Names, or the "Concise" and "Historic" lists. See also
Wikipedia:Reliability of GNIS data.
GR4
The
FIPS55 database, which contains standardized codes for populated places in the
United States. The system describes the codes and the relationships between different entities, such as the part of relationship between a
U.S. state and a
county. It also contains
ZIP code information.[22]
GR5
The
National Geospatial-Intelligence Agency's database of foreign geographic feature names. Excludes information on the United States and
Antarctica. Includes geographical coordinates in the WGS-84 format. Site also includes information on the
FIPS10 standard.[23]
