The given line graph demonstrates data about the number of people using Arabic, Italian, and Greek in Australia as their first languages.
The biggest difference, when compared to others, is China—with its breakthrough development, the use of Chinese has become increasingly popular over 25 years. In 1986, the number was counted at above 100,000, the second lowest among the languages depicted. However, the number increased dramatically, surpassing others to reach the highest position in 2011, with about 350,000 people using it in Australia. Similarly, there was a steady rise in the number of people using Arabic. This trend can be explained by migration from Arab countries from the 1980s up to now. The amount of increase is quite large—100,000 over 25 years—but it is only half compared to the rise in the use of Chinese.
In contrast, there was a significant drop in the number of Italian and Greek speakers over time. The downward trend in Greek started at above 225,000 and fell to just about 175,000 speakers at the end of the given timeframe. A slightly similar decline occurred in the number of Italian speakers, with the smaller population continuing to fall from 150,000 at the beginning to 100,000 speakers in 2006 and remaining unchanged until 2011.
