Is the increase in the number of people in a country in one year

The increase in the number of people in a country over the course of a year is typically referred to as "population growth." This growth can be quantified using various measures, including:

1. **Natural Increase**: This is the difference between the number of live births and the number of deaths in a population over a specific period, usually a year.

2. **Net Migration**: This reflects the difference between the number of people moving into a country (immigration) and those moving out (emigration). Positive net migration contributes to population growth.

3. **Total Population Change**: This includes both natural increase and net migration, providing a complete picture of how a population is changing over time.

Population growth can be influenced by various factors, including economic conditions, healthcare availability, cultural attitudes toward family size, immigration policies, and more.
