Thus, the figures after the 1960 column show the percentage annual growth for the 1955-60 period; the figures after the 1980 column calculate the same value for 1975–80; and so on. The formulas used for the annual growth rates are the standard ones, used both by the United Nations Statistics Division and by National Census Offices worldwide.
English: Bern population pyramid Note: The data here is only (includes) for the permanent resident population, not for those that are non-permanent, however their numbers are miniscule (1034 in total overall) so does not distort the graph to any degree.
Population distribution by age and sex for Angola in 2005. A population pyramid (age structure diagram) or "age-sex pyramid" is a graphical illustration of the distribution of a population (typically that of a country or region of the world) by age groups and sex; it typically takes the shape of a pyramid when the population is growing. [1]
Demographic statistics are measures of the characteristics of, or changes to, a population. Records of births, deaths, marriages, immigration and emigration and a regular census of population provide information that is key to making sound decisions about national policy. [1] [2] A useful summary of such data is the population pyramid. It ...

The 'Foreign' population includes only those who are born abroad and does not discriminate on citizenship.
[clarification needed] The birth rate (along with mortality and migration rates) is used to calculate population growth. The estimated average population may be taken as the mid-year population. [2] [3] When the crude death rate is subtracted from the crude birth rate (CBR), the result is the rate of natural increase (RNI). [4]
From m0 to m85: percentage of those five-year groups of males with respect to the total population. From f0 to f85: percentage of those five-year groups of females with respect to the total population.
In demography and population dynamics, the rate of natural increase (RNI), also known as natural population change, is defined as the birth rate minus the death rate of a particular population, over a particular time period. [1] It is typically expressed either as a number per 1,000 individuals in the population [2] or as a percentage. [3]
