Crude birth rate refers to the number of births over a given period divided by the person-years lived by the population over that period. It is expressed as number of births per 1,000 population. The article lists 233 countries and territories in crude birth rate. The first list is provided by Population Reference Bureau. [1]
Natality is shown as a crude birth rate or specific birth rate. Crude birth rate is used when calculating population size (number of births per 1000 population/year), whereas specific birth rate is used relative to a specific criterion such as age. By calculating specific birth rate, the results are seen in an age-specific schedule of births.
Rates are the average annual number of births or deaths during a year per 1,000 persons; these are also known as crude birth or death rates. Column four is from the UN Population Division [3] and shows a projection for the average natural increase rate for the time period shown using the medium fertility variant. Blank cells in column four ...

Birth rate should not be confused with the generally more useful total fertility rate, which adjusts figures to account for how many females of reproductive age there are.

Replacement fertility is the total fertility rate at which women give birth to enough babies to sustain population levels, assuming that mortality rates remain constant and net migration is zero. [8] If replacement level fertility is sustained over a sufficiently long period, each generation will exactly replace itself. [8]
Vital rates refer to how fast vital statistics change in a population (usually measured per 1000 individuals). There are 2 categories within vital rates: crude rates and refined rates . Crude rates measure vital statistics in a general population (overall change in births and deaths per 1000).
