The optimum population is that ideal size of population which provides the maximum income per head. Any rise or diminution in the size of the population above or below the optimum level will diminish income per head. Given the stock of natural resources, the technique of production and the stock of capital in a country, there is a definite size of population corresponding to the highest per capita income.
Descriptive Statistics and Populations. Consider the fictional countries of Glumpland and Dolmania. The population of Glumpland is 8,442,012. The population of Dolmania is 6,977,201. For each country, the age of every citizen (to the nearest tenth), is recorded in a cell of a Minitab worksheet. Using Stat > Basic Statistics > Display Descriptive Statistics we can quickly calculate the mean age of each country. It looks like Dolmanians are, on average, more youthful than Glumplanders. But is this difference in means statistically significant? To find out, we might be tempted to evaluate these data using a 2-sample t-test.
