The chart illustrates the family income composition among citizens in a certain city. Among all the four categories, full-time income ranked the first, responsible for as high as over 64%. Investment return and part-time income took up the next two largest shares, accounting for 25.2% and 9.5% respectively. Other sources accounted for only 1.2%.
What accounts for the phenomenon? From my view, at least three factors contribute to the phenomenon. To begin with, the phenomenon is closely related to the fast development of national economy and personal wealth. A growing number of families have enough resources to make investment in stock market or real estate. More importantly, the phenomenon has much to do with the turning of people’s attitude and outlook on part-time jobs . Finally, the phenomenon is enhanced and promoted by the government’s bettering employment policies as well as the more convenient channels to seek income outside of citizens’ full-time employment .   
With the development of society, this phenomenon is bound to continue for a couple of years in the future. As far as I am concerned, it’s a positive trend and should be encouraged since it is beneficial not merely to citizens but to the whole society.
