**Population Data for Four States**

Consider the following population table:

| Year | State A     | State B     | State C     | State D     |
|------|-------------|-------------|-------------|-------------|
| 1970 | 11,110,385  | 8,881,826   | 5,195,392   | 3,806,203   |
| 1980 | 11,427,409  | 9,263,044   | 5,490,312   | 4,075,870   |
| 1990 | 11,430,802  | 9,295,397   | 5,544,259   | 4,375,199   |
| 2000 | 12,051,783  | 9,679,152   | 6,045,521   | 4,830,684   |
| 2010 | 12,916,994  | 10,428,783  | 6,392,139   | 5,420,436   |
| 2020 | 13,236,720  | 10,695,793  | 6,627,208   | 5,900,869   |

**Question:**  
How much did the population of State B increase from 1980 to 1990?

**Solution:**  
The population of State B is increased by \[ \] people.

To find the increase in population for State B from 1980 to 1990, subtract the 1980 population from the 1990 population:

Population in 1990 = 9,295,397  
Population in 1980 = 9,263,044  

Increase = 9,295,397 - 9,263,044 = 32,353

Therefore, the population of State B increased by **32,353** people.
