Demographic Transition The concept of demographic transition was first used by Warren Thompson in 1929. Was drawn from the interpretation of the demographic changes experienced by the countries that took part in the Industrial Revolution in the eighteenth and nineteenth centuries, to the present day. From the analysis of these demographic changes has established a pattern that, according to some demographers, it can be applied to other countries, although in historical moments and different economic contexts. The chart "Stages of Demographic Transition" shows the phases of this theory. Phases of the Demographic Transition Source: organized by author. The First Phase (pre-industrial) is marked by the demographic balance and low rates of vegetative growth, supported by high birth rates and mortality. Many are born, but many die. The high mortality was mainly due to poor sanitary conditions, epidemics, wars, famine, etc.. In the second phase (transitional), we have the following changes: at first, the reduction of mortality due to epidemic control and medical advances (arising from the Industrial Revolution), even though the birth rate remains high, causing a large population growth; later, the birth rate begins to fall, then reducing population growth. Finally, in Stage (evolved), the demographic transition is completed with the resumption of demographic balance, now supported by low birth rates and mortality. There are currently at that stage the developed countries, most growth rates has less than 1%, and even negative. In these countries the vegetative growth is stagnant.

Demografska tranzicija Koncept demografske tranzicije prvi je upotrijebio Warren Thompsona u 1929. Izrađen je od tumačenja demografskih promjena doživjeli od strane zemalja koje su sudjelovale u industrijske revolucije u osamnaestom i devetnaestom stoljeću, sve do današnjih dana. Iz analiza tih demografskih promjena je uspostavio uzorak koji, prema nekim demografi, može se primijeniti i na druge zemlje, iako u različitim povijesnim trenucima i gospodarskom smislu. U tablici "Faze demografske tranzicije" pokazuje faze ove teorije. Faze u demografsku tranziciju Izvor: organizira autora. Prva faza (predindustrijskog) obilježava demografskoj ravnoteži i niske stope od vegetativnog rasta, uz potporu visoke stope nataliteta i mortaliteta. Mnogi su rođeni, ali mnogi umrijeti. Visoka smrtnost je bila uglavnom zbog loših sanitarnih uvjeta, epidemija, ratova, gladi, itd.. U drugoj fazi (prijelazni), imamo sljedeće promjene: Isprva, smanjenje smrtnosti zbog epidemije kontrole i medicinski napredak (koji proizlazi iz industrijske revolucije), iako je stopa nataliteta i dalje visoka, što uzrokuje velik porast broja stanovnika; kasnije, natalitet počinje na jesen, a zatim smanjenje rasta populacije. Konačno, u fazi (evoluirao), demografska tranzicija je završio s nastavkom demografskoj ravnoteži, sada podržava niske stope nataliteta i mortaliteta. Trenutno u toj fazi razvijenim zemljama, najviše stope rasta ima manje od 1%, pa čak i negativni. U tim zemljama vegetativni rast stagnira. Pass na glavi ima mnogo djece?
