	NIGERIA		RUSSIA
	Population	Males 15-29	Population	Males 15-29
1991	99,221,845	13,163,335	148,298,707	15,835,923
2011	165,822,569	22,871,161	138,739,892	15,381,389
2031	269,783,151	39,077,293	123,296,462	11,185,095

They both had roughly the same population in 2005 of around 142 million

Just the “additional” 16.2 million males 15-29 added to Nigeria between 2011 and 2031 would currently rank as the world’s  64^th largest country.  39 million males 15-29 (2031) would currently be the 34^th largest country—with 1 million more than Poland and more than 4 times the current population of Sweden.
