The first shows that currently, for every 100 people aged 15-64 there are around 50 younger or older. That allows a rough measurement of dependency notwithstanding that people older than 15 are often still dependent and people over 65 are not.
By 2061, when my children will be in their 60s, there will be around 73-74 dependants for every 100 15-64 year-olds. If nothing changes about the extent of government involvement in health, education and welfare that's a truckload more tax to be paid.
This one simply depicts the increasing diversity of the population. Note that it only projects out to 2026 - not 2061. Not that we didn't know it, but the graph highlights that the Asian population is growing faster than the Maori population. Not something I have a problem with but it is going to bring political tensions and friction.
Finally it has to be said these are projections - they are not written in stone.
