order of migration generation

For #Australia 2016
30-34 is the most common (modal) age for 1st generation migrants
0-4 for 2nd generation migrants
5-9 for the 3+ generation migrants.
The variation in 2nd generation size reflects variations in 1st generation at ages 25-30 years older. #demography pic.twitter.com/qetlHm79V4
