Bangladesh

Boundary data source:

The original database was produced by the National Statistical Office of Bangladesh in collaboration with the UNSTAT/POPMAP Project The original data were compiled in POPMAP which so far does not support true georeferencing. Source map scale and projection were unknown. The data were first transformed into Transverse Mercator Projection (which resulted in the lowest error among several possible projections evaluated) and then projected into lat/long (ie, geographic) coordinates. Rubbersheeting was then performed on the resulting coverage to improve the match with the country and coastal outline from the Digital Chart of the World (DCW). The likely positional error is estimated (= guesstimated) to lie between 500m and 1km (the RMS error in the transformation was below 1000m and rubbersheeting should have improved the fit further). Thus, the coverage is suitable for regional and continental scale applications as well as for visualization of spatial pattern using census data. It should not be used for high resolution applications at the subnational level.

Pop data sources: 1) Bangladesh Central Statistical Office, Census of 1981

1) Bangladesh Central Statistical Office, Census of 1991

digital data obtained from UNSTAT/POPMAP Project

Pop figures computed using the average annual 81-91 growth rate calculated from 1) and 2). In cases where boundaries changed between 1981 and 1991, one of two approaches was taken:

a) if it was clear which district was split into which new districts, the growth rate was assumed uniform for all new districts.

b) if the disaggregation was not clear, the combined growth rate for the entire second level administrative unit was calculated and applied to all new third level units within that second level unit.

Bhutan

Boundary data source:

Database obtained from UNEP/GRID Tsukuba, Japan, based originally on World Data Bank II

Population data source:

District boundaries have changed in a number of instances since. However, no data or detailed boundaries were available for the new units.

POPEST95 estimated assuming constant growth rates across districts and using the

UN World Population Prospects figure as the control total. Basis for estimation were the estimated totals for '85 (based on the 82 census) published in 1).

Brunei Darussalam

Boundary data source:

No subnational boundaries available. National boundaries for the two parts of Brunei were taken from the Digital Chart of the World.

Pop data source:

Pop Data by district for 1981 only. However, no subnational boundaries available. Only the aggregate total for the 3 districts in the Western part:

Muara 114231
Seria/Belait 50768
Tutong 21615

and the remaining total for the disjoint Eastern part

Temburong 6218 (Eastern part)

were used. could be used. Total pop for 1995 from

UN World Population Prospects. These were split in proportion to the 1981 shares for the two regions.

Cambodia

Boundary data source

Boundaries were obtained from the Mekong River Commission Project in Vientiane, Laos (Thomas Hoesli). Approximate scale 1:250,000. The coverage was converted from UTM (Zone 48) into Latlong. The district names were taken from a map produced by the UNITAC Cartographic Unit which had been digitized by the Cambodia National Institute of Statistics for a POPMAP application.

Pop data source:

Population data for 1994 are from the Cambodia National Institute of Statistics and have been obtained in digital form from the UNSTAT/POPMAP Project.

POPEST95 estimated by using the national-level average growth rate for 1990-95 available from the UN World Population Prospects.

For the following three districts no population figures were available Figures for these were estimated assuming the same density as the average for the neighboring districts (this is a highly unreliable estimate!):

Mongkol Borey
Kiri Sakor
Mondul Sema

For three provinces, no second level pop figures were available for any district:

Stoen Treng
Mondol Kiri
Takeo

For these provinces, the 1981 province pop totals from

Department of the Army, Cambodia: a Country Study. U.S. Government, Secretary of the Army: Washington D.C., 1990.

were projected to 1995 using national-level average annual growth rates for Cambodia from the UN World Population Prospects. Growth rate: 3.039 % p.a.

The following districts contained in the POPMAP database were aggregated to form Phnom Penh (DC) district:

Chamkar Mon, Prampi Makara, Don Penh, and Toul Kok.

For Don Penh, no pop figure was available. It was therefore estimated assuming the same density as neighboring Toul Kok district (resulting in 86169 people for Don Penh).

China

Boundary data source:

Coverage of counties for 1980 obtained from National Geographic Society, Washington, D.C. (scale unknown) - see July 1991 issue of NGS Magazine. Coverage was converted from Albers projection into latlong coordinates.

Pop data sources:

1) Estimated 1987 population densities and areas from NGS coverage

Poston, D. & Yaukey, D., The Population of Modern China , Plenum Press, New York: 1992.

Densities were converted into total population and uniformly adjusted in each province to match the published 1990 province totals from 2). The resulting county level estimates were projected to 1995 using national growth rates. The resulting estimates are likely to have limited accuracy.

Potential users of these data are encouraged to contact the Consortium for International Earth Science Information Network (CIESIN) which will soon make a high quality China county coverage for the 1990 available.

Indonesia and East Timor

Boundary data source:

The original database was produced by the National Statistical Office of Indonesia in collaboration with the UNSTAT/POPMAP Project The original data were compiled in POPMAP which so far does not support true georeferencing. Source map scale and projection were unknown. The data were first transformed into a standard projection (chosen as the one with the lowest error among several possible projections evaluated) and then projected into lat/long (ie, geographic) coordinates. Rubbersheeting was then performed on the resulting coverage to improve the match with the country and coastal outline from the Digital Chart of the World (DCW). Based on the RMS error in the transformation, the positional error introduced by these processing steps is estimated (= guesstimated) to lie between 500m and 1km. Thus, the coverage is suitable for regional and continental scale applications as well as for visualization of spatial pattern using census data. It should not be used for high resolution applications at the subnational level.

Pop data source:

Population data from the National Statistical Office of Indonesia, Census of 1990, were also provided by the UNSTAT/POPMAP Project in digital form.

No pop figures available for the following districts in Kalimantan Tengah:

Gunung Mas, Katingan, Barito Timur, and Murung Raya.

Their population was estimated as their area times the average population density of the neighboring districts (12.04 p/sqkm). The accuracy of this estimate is likely to be limited.

POPEST95 derived by using '90 district totals and the district level population growth rate for 1990 as recorded in the Indonesian Census Office/UNSTAT-POPMAP database.

India

Boundary data source:

Coverage of district boundaries for the 1981 census obtained from Birkbeck College, London, Department of Geography. This coverage was updated to correct labeling errors and missing information and to incorporate changes between the 1981 and 1991 census. Various published sources were used for this purpose including:

IndiaMap (see above), was used as a secondary source.

POPEST95 estimated using district level growth rates for the 1981-1991 period. In cases where districts were split between the censuses, the same growth rate was assumed the resulting new districts. The following 1991 districts were created from a single 1981 district:


Arunachal Pradesh:
Tirap & Changlang
West Kamang & Tawang

Assam:

No district level estimates for 1981 available for Assam State - used state level growth rates.

For the areas disputed with / occupied by Pakistan: Gilgit, figure from Europa Publications (statistics for Pakistan, "Northern Areas") for 1981 projected using avg J&K growth rate. Similarly for Chilas, Mirpur ("Azad Kashmir"). Accuracy of the resulting estimates is VERY uncertain! The Pakistani-held parts of this region are known as Azad ("Free") Kashmir, with an area of 4,494 sq miles (11,639 sqkm) and a population of 1,980,000 in 1981, and Northern Areas (including Gilgit and Baltistan), with and area of 28,000 sq miles (72,520 sq km) and a population of 562,000 in 1981.

For these, 1985 figures were estimated assuming the same proportion of people in the municipal and the surrounding province as in 1990. The 1995 estimate thus assumes a constant growth rate in these cases.

Population for 1983 census from 1) by townships (2nd level).

Publications for Arakan (Rakhine) and Chin State provided by Dr. Griffith Feeney (East West Center, Hawaii).

POPEST95 estimated based on '83 township figures and state level growth rates between 1973 (from 2) and 1983 (from 1). The resulting estimates were very low when compared to the total estimated pop in the UN World Population Prospects suggesting an increasing growth rate after 1983. The 73-83 growth rates were therefore uniformly inflated by 1.3 to produce a population total close to the UN estimated figure -> this assumes that the growth rates increased uniformly throughout the country!

Problems: Arakan (Rakhine) State: No township polygon for Rathedaung township (14th township). Pop for this township was therefore added to Ponnagyun into which the town of Rathedaung falls.

Sagaing State: In the coverage, two townships were labeled Sagaing. In comparing with a Myanmar map, one of them was identified to be Sagaing township as it was located around the town with the same name. The other one, further north, was determined to be located around the town of Tantabin and was assigned that label. However, the census pub for this state did not list this township and all other townships were accounted for. But the total population listed for the state minus the total for the townships listed was not the same, and the residual - 32980 - was therefore assigned to Tantabin.

Shan State: Five townships - all located at the North-Eastern border with China - were not listed in the census publication most likely because of security reason - see note from the census publication provided by Griffith Feeney:

"Shan state covers ... and consists of 52 townships. In these townships there are 304 wards and 1632 village tracts. In carrying out the enumeration, 304 wards were fully covered. Out of the total of 1632 village tracts, 1142 were completely covered, 55 were partially covered and 435 were uncovered for security reasons."

Therefore, the residual population between the state total and the total for the 47 listed townships was distributed evenly to the 5 townships which are of approximately even size.

Oman

Boundary data source:

Boundaries do not represent administrative units! Subnational administrative boundaries were unavailable. Instead the main town corresponding to each of the Walayat (2nd subnational level) units was identified, and Thiessen polygons were constructed to derive regions. The resulting coverage provides a crude approximation of political subdivisions and gives a rough idea of population distribution in the country only.

Pop data source:

A few towns (6 and all in Al Wusta Governate/Region) could not be identified. All of these had a very low population of about 10k or less. Their population was distributed proportionately to the remaining towns in the Governate/Region. 1993 figures were extrapolated using national growth rate from the UN World Population Prospects.

A new district, Kilinochchi, was created in 1986. However, the boundaries for this district were not available. Similarly, the 1981 figures for this new district based on the census were not published. From the location of Kilinochchi town, and an examination of growth rates for the districts in its vicinity, it was judged that the new district was created from Jaffna district rather than from Mullaitivu. The '89 and '92 pop for Kilinochchi (97,000 and 104,000 respectively) were therefore added to Jaffna district total (raising its 81-92 growth rate to 1.49 from 0.47).

POPEST95 estimated using calculated district level growth rates from 1989 to 1992 from 1).

Sri Lanka did not have a census since 1981. All censuses have been cancelled until further notice.

POPEST95 based on average annual growth rates calculated using 1990 census figures from 1) and 1980 figures from 2). To account for the very large resulting estimate (possibly due to declining fertility rates = declining growth rates), a deflator of 0.7 was used to adjust the growth rates downward. The deflator was chosen so that the total pop for Thailand matched the total pop estimate for the country published in UN World Population Prospects.

Nakhon Phanom province in the Northeastern Region (across the border from Laos (Savannakhet) was split between the 1980 and 1990 census to create the new province Mukdahan.

Boundary data source:

The original database was produced by the National Statistical Office of Vietnam in collaboration with the UNSTAT/POPMAP Project The original data were compiled in POPMAP which so far does not support true georeferencing. Source map scale and projection were unknown. The data were first transformed into a standard projection (chosen as the one with the lowest error among several possible projections evaluated) and then projected into lat/long (ie, geographic) coordinates. Rubbersheeting was then performed on the resulting coverage to improve the match with the country and coastal outline from the Digital Chart of the World (DCW). Based on the RMS error in the transformation, the positional error is estimated (= guesstimated) to lie between 500m and 1km. Thus, the coverage is suitable for regional and continental scale applications as well as for visualization of spatial pattern using census data. It should not be used for high resolution applications at the subnational level.
