these are self-described families. 45% of families represent a couple with children, 11.% represent a sole-parent family and 43.1% are couples without children (or whose children have left home). The large number of couples without children (5.6% higher than the Adelaide average) owes to the sizeable elderly population. Almost a quarter (23.7%) of the population is aged 60 or over, almost a third (29.9%) is 24 or younger; mature adults are the largest population group at 46.4%. This would indicate a structure primarily of mature families and retirees, young adults are hugely unrepresented (although this is not unique to Burnside, this phenomenon is common throughout the majority of the Adelaide region); the 18-24 age group suffered a loss of 330 people between 1996 and 2001. 26.3% of the population was born abroad, less than the Adelaide average. 9% of the population came from English-speaking countries, while 14.3% did not. In decreasing order, the foreign-born population was from the United Kingdom, Italy, Malaysia, New Zealand, Germany, Greece, Hong Kong, India, China and South Africa. These patterns are broadly in-line with that of Australia as a whole; they reflect traditional immigration from Commonwealth countries such as the United Kingdom and New Zealand, later waves of Mediterranean migrants and more recent arrivals from Asia. Religious adherence in Burnside is higher than the Adelaide and Australian average, standing at 71.7%. Of this adherence, 67.6% represents traditional Christian denominations. Common across Australia and many developed countries, there has been a substantial decline in religiosity; this is evident but less marked in Burnside; 17.7% of residents profess no religious belief (atheism, agnosticism, etc.). The ten strongest religions/denominations in decreasing order are: Catholic, Anglican, Uniting, Orthodox, Lutheran, Baptist, Buddhism, Presbyterian, Judaism and Hinduism. Catholicism is unique for its marked increase (575 persons) in believers between 1996 and 2001, most other religions' numbers remained stable or saw a slight decrease. Economy Burnside has no manufacturing industries and a small number of agricultural plots still exist in the form of vineyards. It does however contain a sizeable amount of service industry; high-technology and commercial offices line the streets opposite the Adelaide park lands. Burnside workers are employed in the Industries of Education, Health and Community Services (27%); Finance, insurance and business services (22.5%); wholesale and retail trade (16%); recreation and personal services (11.2%) and manufacturing (7.7%). In these industries they are employed as: Professionals (35.5%); clerks, salespersons and service
