Doubling time; the time it would take a population to double, given there are no changes in age-specific mortality or fertility rates |

| rm |
Intrinsic rate of increase; a measure of the rate of growth of a population. This assumes the population is in stable age distribution. It is equal to the natural log (In) of the finite rate of increase |
| Ro |
Net reproduction rate; the average number of offspring an individual female will produce in her lifetime. Unlike the GRR, Ro depends on age-specific mortality rates |
| .RTB |
CGIAR Research Program on Roots, Tubers and Bananas |
| SSA |
Sub-Saharan Africa |
| T |
Generation time; the average age at which a female gives birth to her offspring. This is equivalent to the time it takes for a population to increase by a factor equal to the net reproductive rate. |
