I hear what you say snail but overall there isn't an increase but a decrease and its set to continue for a while here's an article that shows whats happening in Bulgaria. although I do know that there is an influx from various places round the world I don't think its going to have any impact of property prices for some time to come.
The population of Bulgarian has decreased to 7.563 million, returning to the 1956 figure, Bulgarian National Television said on August 23 2010.
The difference is that the life expectancy of Bulgarians has increased from 1956 levels, by 10 years for women, up to 77, and by five years for men, up to 69.
According to the report, more than 80 000 babies were born in Bulgaria in 2009, but in spite of this, there is a persistent negative birth rate, currently at negative 3.5 in 1000 people, which nevertheless marks an improvement from 2005, when it was at its record 5.4 in 1000 people.
About 428 centenarians live in Bulgaria, while there are 3186 Bulgarians who are close to turning 100 year old, aged between 95 and 99.
Bulgaria’s population at the end of 2009 was 7563 710, a figure 0.6 per cent lower than in 2008 but representing the lowest rate of population decrease since 1993, according to National Statistical Institute (NSI) figures released on March 24 2010.
The decrease in the population was attributed to emigration and a continued negative birth rate. The deficit between deaths and births was 27 112.
This data has long since been deemed obsolete with many Bulgarians freely working and living outside Bulgaria since the country's accession to the European Union in 2007.
Women were 51.6 per cent of the population in Bulgaria, which as a whole had an average age of 41.8 years.
In Bulgaria, 71.4 per cent of people were living in cities, according to the National Statistical Institute.
The working-age population at the end of 2009 accounted for 63.1 per cent, but the figure was 32 000 lower than the previous year.
A total of 1700 foreign nationals were registered as living in Sofia in 2009, the NSI said on April 15 2010.
The average age of men in Sofia was 38.6, while the average age of women in Sofia in 2009 was 42.2. For every 1000 men there were 1102 women, NSI data said.
