In recent years, Australians have been waiting longer before getting married for the first time and the number of long-term de facto couples is also on the increase. These trends may have some effect on Australian society and government policies. The table below presents the age- specific marriage rate (in percentage) of Australian males and females by age group for the years 1993 and 2013.
