The Census statistics make for some interesting reading.
I've gone back to the 1996 Census to get a longer perspective of the trend.
This is a 17-year period and indicates the result that has been reported in the media is not a recent phenomenon. Rotorua has been static in its population over that time, growing by just 771 residents - an average of 45 per year.
This is an annual growth rate of 0.07 per cent. As a comparison, Hamilton has grown by 29 per cent with an increase in population of 31,830, or an annual growth rate of 1.65 per cent. But even that stellar performance is put in the shade by Tauranga. An annual growth rate of 2.45 per cent, given a total increase of 37,008, or a growth of 47.6 per cent in 17 years.
Put in other words, Tauranga has increased its population by nearly half again in the past 17 years.
