Which countries are growing the fastest by population?

Phil A did what I wanted. Thanks to him. I only need to analyse the table he provided above.

Most in Africa (particularly those lower in Economic development) & some in West Asia are growing fastest. Without even batting an eye-lid, most people jump to the conclusion that large population in numbers have big "population growth" (devoid of elementary common sense) too, that you asked for. Those leading in population growth rate are here (below), with population doublesng in less than 25 years:

Niger 4.1 %

Oman 3.65 %

Burundi 3.34 %

Uganda 3.31 %

Chad 3.27 %

Angola 3.23 %

Gambia 3.22 %

South Sudan 3.19 %

DR Congo 3.18 %

Tanzania 3.15 %

Zambia 3.12 %

Malawi 3.11 %

Iraq 3.09 %

Mali, Senegal 3.04 %

Kuwait 2.96 %

Burkina Faso 2.92 %

Equatorial Guinea 2.9 %

Madagascar 2.81 %

Mozambique, State of Palestine 2.76 %

Somalia 2.71 %

Nigeria, Togo 2.63 %

Rep. of Congo, Kenya 2.61 %

Comoros 2.36 %

Rwanda, Lebanon 2.35 %

Sudan 2.34 %

For comparison I give rates of some developed (or -ping) countries: USA is growing faster than China. Countries like Russia & Estonia have negative growths (population is dwindling)

China 0.46 %

India 1.2 %

USA 0.73 %

Brazil 0.83 %

South Africa 0.9 %
