Malaysia - Description of Methodology
1.
Political Boundaries:
Peninsular Malaysia located between latitudes 1 and 7 north and longitudes 100
and 104 east, situated right in the heart of South East Asia is a federation of 13
states and two distinct regions: Peninsular Malaysia and the East Malaysian
provinces of Sabah and Sarawak in North Borneo. The two parts are separated
650km (403 miles) apart by the South China Sea. Peninsular Malaysia's neighbors
are Thailand and Singapore. Sabah and Sarawak border Kalimantan (the
Indonesian part of Borneo) and Sarawak surrounds the tiny enclave of Brunei.
The Andaman Sea is on the West Coast of the peninsula. The East Coast of the
peninsula, Sabah and Sarawak all adjoin the South China Sea. It is hot and humid
all year round and its natural vegetation is the tropical rainforest. Total land area
is about 328550 Sq. Km.

Data Sources:
Population:
Area and 1991 population for states/administrative regions was obtained from
"Yearbook of Statistics Malaysia 1992 and 2000," published by the Department of
Statistics, Malaysia. To keep the data consistent with our analysis, the 1991
population was rescaled using weighted average to fit the 1990 population.
Population density was calculated for each province for computing the expected
population in grid. GWP population figures were used rescaling the population in
grid.
RIG’s:
The file Malaysia_Province was obtained from the g-econ server. The file,
contained state/region level information regarding long., lat., RIG’s, ZPop and
Grid Area was created by Steven Citron_Pousty or Kyle Hood. Arc View
Program was used to compute State/Region level RIG’s for the present analysis.
ArcView shows 14 administrative division that are included 13 states/regions:
Johor, Kedah, Kelantan, Kuala Lumpur, Melaka, Negeri Sembilan, Pahang,
Perak, Perlis, Pulau Pinang, Sabah, Sarawak, Selangor, Terengganu. RIG’s
figures calculated using Arc View program and obtained from the
Malaysia_Province file were found to be comparable.
GDP:
Per capita GDP figures for the year 1990 for the States/Region were obtained
from the "Sixth Malaysia Plan, 1991-1995," published by the Government of
2
Malaysia. The GDP figures were rescaled to fit the 1990 current prices and were
used to compute the cell out put.
Methodology:
“GDP by province” methodology:
We have the state/region wise data on population, density and per capita GDP.
First the grid area figures were converted into square kilometers using 1 square
mile = 2.59 square kilometers. Then, the sub cell population was computed using
the formula [RIG * grid area * population density], and re-scaled the resulting sub
cell population to fit the GWP population. Sub cell GDP was calculated using the
formula [sub cell GDP = [income per capita * 1990 sub cell population], where
income per capita = [total GDP/Population], and aggregated the sub cell values to
the cell level using the "collapse" command in Stata. Finally, cell GDP was rescaled to fit the 1990 National GDP of the county and re-scaled further to fit the
1990 World Bank GDP (Constant 1995 US $).
