This template quickly calculates the population growth rate given two pairs of years and populations using the formula from Population growth:
At the 2011 census, the population inhabiting Bulgaria was 7,364,570 in total, but the 2021 Census calculated that the population had declined to 6.5 million. [ 6 ] [ 7 ] The peak was in 1989, the year when the borders opened after a half of a century of communist regime, when the population numbered 9,009,018.
The number shown is the average annual growth rate for the period. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship—except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of the country of origin ...
Population density (people per km 2) by country. This is a list of countries and dependencies ranked by population density, sorted by inhabitants per square kilometre or square mile. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.
2. During the period 1910 - 1920 the population growth in Bulgaria was as follows: It is estimated that about 350,000 refugees were sent to Bulgaria, losing territories during the Balkan War ll and the World War I.
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 ...
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.
A population projection, in the field of demography, is an estimate of a future population. It is usually based on current population estimates derived from the most recent census plus a projection of possible changes based on assumptions of future births, deaths, and any migration into or out of the region being studied.
