A problem of estimating a contingency table arising in demographic analysis
Population Studies
|November 15, 2011
Summary
This study estimates births and deaths in Malaya during the Japanese occupation (1942-45). Demographic data reveal reduced births and increased deaths, particularly impacting Chinese and Indian communities in states with smaller Malay populations.
Area of Science:
- Demographic analysis
- Historical demography
- Population studies
Background:
- The Japanese occupation of Malaya (1942-1945) significantly impacted demographic trends.
- Specific adverse effects were noted for the Chinese and Indian communities.
- Estimating vital statistics during this period presents unique challenges.
Purpose of the Study:
- To estimate the numbers of births and deaths in Malaya.
- To provide cross-classifications by state and race for the occupation years.
- To analyze the demographic impact on different ethnic groups and regions.
Main Methods:
- Development of a specialized estimation technique for contingency tables.
- Incorporation of the specific demographic situation during the Japanese occupation.
- Analysis of vital statistics considering state and race.
Main Results:
- Significant reduction in birth numbers observed.
- Notable increase in death numbers recorded.
- Disproportionate impact on Chinese and Indian communities, especially in states with lower Malay populations.
Conclusions:
- The estimation technique effectively captures demographic shifts during the occupation.
- The Japanese occupation led to adverse demographic changes in Malaya.
- Regional and ethnic disparities in demographic impact were evident.

01:29Contingency Table
A contingency table provides a way of portraying data that can facilitate calculating probabilities. It is a method of displaying a frequency distribution as a table with rows and columns to show how two variables may be dependent (contingent) upon each other; The table helps determine conditional probabilities quite quickly and can help systematically organize, analyze and quantify data. The table displays sample values concerning two variables that may be dependent or contingent on one...
01:08Determination of Expected Frequency
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...
01:21Introduction to Test of Independence
In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

01:22Life Tables
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...
01:25Choosing Between z and t Distribution
The z and the Student t distribution estimate the population mean using the sample mean and standard deviation. However, to decide which distribution to use for a calculation, one needs to determine the sample size, the nature of the distribution, and whether the population standard deviation is known. If the population standard deviation is known and the population is normally distributed, or if the sample size is greater than 30, the z distribution is preferred. The Student t distribution is...
01:16Hypothesis Test for Test of Independence
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
