Looking into the 2006 Census stats on relationships reveals some interesting facts.
Three males aged 15-19 in Canberra are married and another 79 are in defacto relationships. On the other side of the ledger, 34 females aged 15-19 in Canberra are married and another 224 are in defactos.
This trend of more females in relationships than males for a given age group continues through the age groups until above 55 years where there are more males in relationships than females.
So it would appear that Canberran men prefer to marry younger women.
