According to United Nations data, the population of sub-Saharan Africa increased from 220 million in 1960 to 1.1 billion in 2017. 
To calculate the percentage increase, we can use the formula: 
Percentage increase = (final value - initial value) / initial value * 100%
Plugging in the numbers, we get: 
Percentage increase = (1.1 billion - 220 million) / 220 million * 100% 
Percentage increase = 880 million / 220 million * 100% 
Percentage increase = 4 * 100% 
Percentage increase = 400% 
Therefore, the population of sub-Saharan Africa increased by 405% (rounded off) from 1960 to 2017.
