Problem Analysis

To solve this problem, we need to calculate the change in population for both the kingdom and the state. We are given the initial population for each and the number of people who moved between them. We need to subtract the number of people who moved back from the total number of people who moved from one place to another.

Solution

Let's calculate the change in population for the kingdom and the state.

1. Initial population of the kingdom: 244,365 2. Initial population of the state: 218,875 3. Number of people who moved from the kingdom to the state: 13,262 4. Number of people who moved from the state to the kingdom: 11,128 5. Number of people who moved back from the kingdom to the state: 3,116

To calculate the change in population for the kingdom, we subtract the number of people who moved from the kingdom to the state and add the number of people who moved from the state to the kingdom:

Change in population for the kingdom = (Number of people who moved from the kingdom to the state) - (Number of people who moved from the state to the kingdom)

Change in population for the kingdom = 13,262 - 11,128 = 2,134

To calculate the change in population for the state, we subtract the number of people who moved from the state to the kingdom and add the number of people who moved back from the kingdom to the state:

Change in population for the state = (Number of people who moved from the state to the kingdom) - (Number of people who moved back from the kingdom to the state)

Change in population for the state = 11,128 - 3,116 = 8,012

Therefore, the population in the kingdom increased by 2,134 people, and the population in the state increased by 8,012 people.

Answer

The population in the kingdom increased by 2,134 people, and the population in the state increased by 8,012 people.
