The given diagrams illustrate three distinct types of workers determined by their born places and the unemployment rates in these groups from 1993 to 2003 in Australia.
Overall, among types of Australian workforces, the workers born in Australia constituted the highest, whereas the unemployment rate in three sectors witnessed a downtrend throughout the period shown, with the non-English-speaking countries group being prominent among the others.
Starting with the pie chart, it is apparent that the number of native Australian workers accounted for the highest, at 76%. In contrast, the figure for the non-English-speaking (NESC) and English-speaking (ESC) groups occupied a negligible percentage, at 14% and 10% respectively.
Turning to unemployment levels, in 1993, the NESC workers accounted for 7%, followed by a constant decrease in the subsequent years. In 2000, the figure hit the lowest point, at around 3%, and remained relatively stable over the remaining years. A similar trend could be observed in native Australia and ESC groups. Starting at nearly 4% each and desceneding to above 2% and below 2% respectively.
