Wrong Division Result

[Zenith1900]

Why cant i get a result from division, it always comes out to 0.

#include<iostream>
#include<iomanip>
#include<vector>
using namespace std;

int main()
{
	vector<int> population;
	vector<int> birth;
	double birthRate;
	int Cities;
	int index;

	cout<<"How many cities do you have";
	cin>>Cities;
	for (index=0; index<Cities; index++)
	{
		int tempPop;
		double tempBirth;
		
		cout<<"Population for city  " << (index+1) << ": ";
		cin >> tempPop; 
		population.push_back(tempPop);
		cout<<"Births for city  " << (index+1) << ": ";
		cin >> tempBirth;
		birth.push_back(tempBirth);
		
    }
		for (index=0;index<Cities; index++)
		{
			birthRate = birth[index] / population[index];
			cout << "Birthrate for city #" << (index+1) <<": "<< birthRate<< endl;
		}
	
 return 0;
}

You cannot get fractions from integer division, so atleast one of the values you are dividing has to be a double or float. Try casting
