The article discusses the problem of demographic crisis in Bulgaria. Suggested are some foreign reserves to improve the demographic situation. These reserves may be: persons with Bulgarian citizenship in countries around the world; Bulgaria-born persons living abroad; persons from countries similar in language and culture to the Bulgarians; immigrants from countries where the main religion is Christianity; immigrants from countries where the main religion is different from Christianity - Islam, Buddhism, Hinduism, Judaism and others. Discussed are the advantages and disadvantages of each of the reserves. The number of Bulgarian nationals outside Bulgaria for 2011 was over 0.5 million of which over 90% are in countries of the European Union. The number of people born in Bulgaria and abroad as per 2011 is over 1 million. From these in European Union are 50% and in Turkey - 40%. Persons of Bulgarian ethnicity and ancestry (in countries where this is registered) outside Bulgaria are over 0.5 million. Those categories in some parts partially overlap and blend into one another. Therefore, the total amount of reserve from all sources is estimated to be 0.5 - 1 million people.
