Increase in population.
Workers are going to developed countries in search of better-paying jobs.
natural increase + net migration = population change
b mass migration
Population density
Migration can affect population distribution by causing the population of one area to increase while simultaneously decreasing the population of another. This can also cause one area to be more densely populated than another.
The size of a population can get larger with no influences from migration if birthrate is greater than the death rate. This results in a natural increase in population size due to more individuals being born than those dying.
That's a terrible answer and there is absolutely no logic backing it. First you need to understand the meaning of migration, which is the movement of people both ways - people leaving and coming into a country. Migration may cause a population increase, undoubtedly if there are more people coming into a country than going out, but this would also also increase a countries demand for services and facilities, opening up jobs in fields like construction, healthcare etc and reducing the unemployment rate which results in more tax revenue and national output which will increase the economy and leave the government with more money to spend as well as more personal income. An increase in population is not always a bad thing if it is done in a controlled way.
The increase in the proportion of the population residing in the towns brought about by migration of rural populations into towns and cities
Take the original number o and the new number n . Subtract the smaller from the bigger. Then divide the difference by the original number. Put that number into a percent Take the original number o and the new number n . Subtract the smaller from the bigger.Then divide the difference by the original number. Put that number into a percent
the population will increase. However, that assumes that net migration is also constant - or does not change sufficiently.
The Industrial Revolution, which started in the late 18th century, paved the way for significant technological advancements in agriculture, medicine, and sanitation. These improvements led to better living conditions, reduced mortality rates, and increased food production, resulting in a rapid increase in human population around 200 years ago.
