If a city of 10,000 experiences 200 births, 60 deaths, 10 immigrants, and 30 emigrants in the course of a year, what is its net annual percentage growth rate?

Solution:

200 births and 10 immigrants will be added to the population. Total is 210.

60 deaths and 30 emigrants will be taken away from the population. Total here is 90.

Just a reminder that an emigrant is somebody who leaves their own country to lastingly settle into a different country.

Therefore, 210 people are added to the population, and 90 people are to be subtracted, for a net gain of 210 - 90 = 120 people.

What percentage is 120 of 10,000?

120/10,000 = 0.012 = 1.2% annual growth rate

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
