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]
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 ...
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.

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.

The formula for standardized rates is as follows: [citation needed] Σ(crude rate for age group × standard population for age group) / Σstandard population See also
Birth rate and mortality rates can change rapidly due to disease epidemics, wars and other mass catastrophes, or advances in medicine and public health. The UN's first report in 1951 showed that during the period 1950–55 the crude birth rate was 36.9/1,000 population and the crude death rate was 19.1/1,000.
