In close cooperation with the Directorate-General of Statistics and Economic Information (DGSEI), the Federal Planning Bureau produces long-term population projections on a regular basis. First, demographic data from the National Register are consolidated by the DGSEI. Subsequently, based on those statistics for the years 2007, 2008 and 2009 which lead the observed population on 1 January 2010, the Federal Planning Bureau established new population projections. The latter replace the population projections 2007-2010 available on the websites of both institutions up to that moment. Since their completion in April 2011, the new population projections are employed in the FPB’s various economic projection activities and were as such integrated in the preparatory activities to the government formation.
More than before, the continuous increase in life expectancy and, especially, the recovery of the fertility rate among Belgian women - in particular in the Brussels and Flemish Regions - and the increased international immigration over the past years contribute to the future population growth. In 2060, the population in Belgium and in the Brussels Region (equaling 10.839.855 and 1.089.568 persons, respectively, on 1 January 2010) should amount to 13.515.000 and 1.475.200 persons, respectively. In addition, the population should be younger than anticipated before, yet the old age dependency ratio for Belgium should still increase considerably from 26 elderly persons per 100 active persons in 2010 to 42 in 2060 (compared to 45 in the previous projection).
