The table provides a comprehensive breakdown of New Zealand’s population distribution by age group from 2011 to 2012. It is evident that while the overall population remained relatively stable, significant changes occurred within specific age categories.
Firstly, the number of children and middle-aged adults (ages 0-14 and 15-39) declined slightly by 0.2% over the period. This minor decrease contrasts with the age group 40-64, which experienced a more substantial increase of 0.6%. However, the most dramatic shift was observed in the senior age group (65 and over), which saw an impressive rise of 4%. This percentage represents a substantial growth rate, significantly higher than that of any other age group.
Overall, despite the overall population’s stability, there was a slight net increase of 0.6%, predominantly driven by the notable growth in the senior demographic.
In summary, the data illustrates a stable total population with pronounced changes within specific age brackets. The considerable increase in the senior population highlights a demographic shift that has substantial implications for New Zealand’s population structure.
