Explanation:
Analyzing the problem:
By 2010, population of town = 70,230
Population trend in a 5 years period:
migration
immigration: 6556
emigration: 4096
Birth 5225
Death 4978
Unknown:
The population of the town in 2015 = ?
Solution:
immigration and birth are positive factors on population
Death and emigration removes from a population
Therefore, the population in 2015 will be:
= Population 2010 + immigration + birth - death - emigration
= 70230 + 6556 + 5225 - 4096 - 4978
= 72,937
