The provided line graph gives detailed information about the number of individuals who used Chinese, Arabic, Italian, and Greek as their mother tongue in Australia.
Looking from an overall perspective, it is readily apparent that the number of Australians whose native language was Italian and Greek experienced a downward trend. The opposite was true for the figures for Chinese and Arabic throughout the period. Chinese surpassed other languages and became the most popular first language in Australia, while Italian was the lowest figure.
In 1986, the total number of people who spoke Chinese was just over 100,000, followed by Greek, approximately 230,000, Italian, at 150,000, and lastly, Arabic was very low, about 50,000. By 2001, Chinese and Arabic language users rose dramatically to 250,000 and 105,000, respectively. Greek declined slightly to 200,000, and Italian experienced a gradual reduction to 106,000.
Over the last ten years, the Chinese population has continued to increase and reached 350,000 by the end of the year. Arabic language users increased the same and by 2011 recorded at 150,000. The year 2006 noted 100,000 Italian native speakers, and remained unchanged until 2011. The Greek speakers fell from 200,000 to 180,000 by the end of the year.
