Definitions and references
Interstate arrivals - arrivals from other states or territories of Australia who intend to stay permanently.

Long-term arrivals - persons arriving from overseas who intend to stay in Australia for one year or more and Australian residents returning from an overseas visit of one year or more.
Reference: Overseas Arrivals and Departures, Australia (cat. no. 3404.0)
Long-term departures - departures of Australian residents who intend to stay temporarily overseas for one year or more and departures of visitors who had stayed in Australia for one year or more.
Median age - the age at which half the population is older and half is younger.
Net interstate migration rate - interstate arrivals minus interstate departures during the year, expressed as a proportion (per cent) of the population at the beginning of the year.
Net overseas migration rate - permanent and long-term arrivals minus permanent and long-term departures during the year expressed as a proportion (per cent) of the population at the beginning of the year.
Net reproduction rate - the number of daughters that a cohort of newborn female babies will bear during their lifetime, assuming fixed age-specific birth rates and a fixed set of mortality rates.
Non-English speaking countries - all overseas countries except United Kingdom, Ireland, New Zealand, South Africa, Canada and the United States of America.
Permanent arrivals - persons arriving from overseas with the intention of settling permanently in Australia. It includes those with migrant visas, (regardless of stated intended period of stay), New Zealand citizens who indicate an intention to settle, and those who are otherwise eligible to settle, e.g overseas born children of Australian citizens.
Permanent departures - Australian residents, including former settlers, who on departure state that they do not intend to return to Australia.
Population projections - the ABS produces population projections using the cohort component method which takes a base year population for each sex by single years of age and advances it year by year by applying assumptions about future mortality and migration. Assumed age-specific fertility rates are applied to the female populations of child-bearing ages to provide the new cohort of births. This procedure is repeated for each year in the projection period for each state and territory and for Australia. The ABS produces several series of population projections based on different combinations of assumptions about mortality, fertility and migration. The assumptions underlying Series A most closely reflect prevailing trends and comprise: declining rates of mortality; a constant level of fertility (total fertility rate of 1.88 for Australia); low levels of overseas migration (rising to 70,000 per year by the year 2000 then remaining constant); and continuing high levels of interstate migration.

Rate of natural increase - the excess of births over deaths during the year expressed as a proportion (per cent) of the population at the beginning of the year.
Refugee arrivals - comprises: those who arrive under the refugee program (which provides protection for people who have fled their country because of persecution); those who arrive under the humanitarian programs (those who leave their country because of significant discrimination amounting to gross violation of human rights); and those who arrive under the Special Assistance Category (groups determined by the Minister to be of special concern to Australia and in real need but who do not come under the traditional humanitarian categories. It includes those externally displaced people who have close family links with Australia).
