Generation Y has a big population and in few years they will be the biggest. Baby boomers (born 1946-1964) is the biggest and most numerous generation for now but they will retire in the next years. Generation X (born 1965-1979) has smaller population than the other two.
Hinar tvær eru uppgangskynslóðin (1946-1964), sem er stærsta og fjölmennasta kynslóðin og mun fara á eftirlaun á næstu árum og X-kynslóðin (1965-1979) sem er mun minni kynslóð en hinar tvær.
