Population 1 January 2012
The population on 1 January 2012 was 319,575 compared with 318,452 in 2011. This constitutes an increase of 0.4%. The population declined in four regions, mostly in the Northwest which lost 2.6% of its population in 2011. Five regions experienced a population increase. The Southwest gained the most where the population increased by 154 persons, or 0.7%.
The number of municipalities by 1 January 2012 was 75, down by one in 2011 due to the merging of two small municipalities in the Westfjord and Northwest regions. Five municipalities have fewer than 100 inhabitants, and 42 have fewer than 1,000 inhabitants.
The dependency ratio was 68.4% on 1 January 2012, a slight increase from previous year when it was 68.1%. The dependency ratio is calculated as the ratio of the young and old to the working age population of 20–64 years of age.
The number of nuclear families, i.e., couples with or without children under the age of 18 years or parents with children under 18 years, was 77.621 on 1 January 2012, compared with 77,370 families in 2011.
The population development in 2011 will be further analysed in the Statistical Series, due to be published 3 April this year.
Due to the merging over borders, the Northwest region has been expanded to cover the former municipality of Bæjarhreppur in the Westfjord region.
A new definition of localities and urban nuclei has been introduced, following closely international recommendations, especially that of the Commission Regulation (EC) No 1201/2009 implementing Regulation (EC) No 763/2008 of the European Parliament and of the Council on population and housing censuses as regards the technical specifications of the topics and of their breakdowns (OJ L 329, p. 29, 9 15.12.200).
As previously announced, mid-year population figures have been replaced by annual average population figures. Those are calculated simply by averaging the start and end figures of the year.
