Sure, let's solve this problem step by step:
1. Identify the total population of the city:
The total population is given as 500,000.
2. Identify the population of females and males:
The population of females is 130,600 and the population of males is 160,300.
3. Calculate the combined population of females and males:
Add the female population and the male population together:
[tex]\[
130,600 + 160,300 = 290,900
\][/tex]
4. Calculate the number of children:
Subtract the combined population of females and males from the total population:
[tex]\[
500,000 - 290,900 = 209,100
\][/tex]
Therefore, the number of children in the city is 209,100.
