Migration can be calculated by subtracting the number of individuals leaving a particular area from the number of individuals entering that area over a given time period. This can be done at various scales, such as national or regional levels, and can be measured using census data, surveys, or other population monitoring methods. Additionally, migration rates can be calculated by dividing the number of migrants by the population size and multiplying by 100 to obtain a percentage.
simple random sampling
Divisor
Dividing by decimal is different from dividing by whole number as you have to multiply by a number to remove the decimal.
If you are dividing a positive by a negative, yes. If you are dividing a negative by a negative, you will get a positive.

Cluster Sampling
It is called one-stage cluster sampling. If random samples are taken within the selected clusters then it is two-stage cluster sampling.
To calculate population density, two pieces of information are needed: the total population of a specific area and the land area of that same area. By dividing the population by the land area, population density can be determined, usually expressed as the number of individuals per square unit (e.g., individuals per square mile or individuals per square kilometer).
Population density is calculated by dividing the population of a region by its land area. This measurement helps to determine how crowded or sparsely populated an area is.
Dividing the population by the area the population occupies gives population density.
By taking a sample of the entire population.
The number of people who die per one thousand individuals in a population per year is referred to as the crude death rate. It is a measure of the mortality or death rate in a population and is calculated by dividing the number of deaths in a year by the population size and multiplying by 1000.
Population density is the size of a population that occupies a specific area. It is calculated by dividing the total population by the area they inhabit, usually expressed as individuals per square kilometer or square mile. It is a useful measure to understand how crowded or dispersed a population is in a given area.
Stratified sampling is a type of sampling that uses a fair representation of the population by dividing the population into different subgroups or strata and then selecting samples from each stratum in proportion to their size in the population. This method helps ensure that all groups in the population are adequately represented in the final sample.
Coffee is a homogeneous mixture (assuming it has been well-stirred), as the mixture has a uniform composition throughout. Dividing the mixture into macroscopic parts, each part will have the same composition as the original mixture.
