This paper examines the role which different demographic groups (youth, persons of prime working age and older persons) have played in the overall change of the labour force (reproduction), changes in the educational attainment and changes in the distribution of occupations. This paper uses the pseudo-cohort analysis and cross-sectoral data collected from the Labour Force Survey. Main findings show that the educational attainment of new entrants into the labour force was higher than that of retiring workers over the time period of 2004-2014. The composition of occupational changes over the decade confirmed what had been observed for the educational attainment of the labour force. Young new entrants into strongly growing occupations (most of which were highly skilled) by far outnumbered the retirees over the past decade.
