Presented is a line graph that provides detailed statistics about the number of Australians who use Chinese, Arab, Italian, and Greek as their first language.
At a glance, it is obvious that the most prevalent language used by Australian people is Chinese. While the figure for using Chinese and Arabic witnessed an upward trend, the reverse is true for Greek and Italian during 25 years.
Delving deeper, the number of Australian individuals used Chinese increased gradually 50,000 people every 5 years, commenced at around 100,000 people and ended at 450,000 in 2001. Following a similar trend, a remarkable hike was recorded for Arabic, which was the lowest point in 1986 (50,000 people), surged to 150,000 people after 25 years.
In contrast, there was a marginal dip in the number of people who used Greek, from 220,000 to 200,000 people in the first 10 years, and fell continuously to 180,000 people in 2011. Notably, the number of Australians who spoke Italian exhibited a descent by 50,000 people from 150,000 people in the first 20 years, this was followed by a level off at 100,000 people by the end of the period.
