Final answer:
The question deals with mathematical concepts of percentages and population statistics, where population figures are used to calculate ratios and percentages relevant to total and subgroup populations.
Step-by-step explanation:
This question appears to be related to the calculation of percentages and population statistics, which are key concepts in mathematics, particularly in the area of statistics and probability. The provided data includes various population numbers in different years and ethnic groups, as well as percentages related to the total populations.
To determine the total population or percentages, one would typically sum the figures provided or calculate the ratio of a subgroup to the total, converting it into a percentage by multiplying by 100. For example, if you're trying to find what percentage of the total population is represented by a given ethnic group, you would divide the population of that ethnic group by the total population and then multiply by 100 to get the percentage.
