Iraq: $1.9\%$ a year

$A=A_{0}e^{kt},$ where $A$ is the population after $t$ years, $A_{0}$ is the initial population, $k$ is the growth rate if $k>0$ or a decaying rate if $k<0$. Only India and Iraq have growth rate. Because $0.019>0.008$ it follows that Iraq has the greatest growth rate at $k=0.019$ and its population is growing at $1.9\%$ a year.
