The given bar chart provides the proprotion of families in China which only had one son or one daughter in three regions: urban areas, suburbs and countryside over a period of twenty years starting from 1980 to 2000.
Overall, the 20-year-period switnessed a quitely significant shift in the percentage of single-child households in China. The rate of three regions which had one child experienced a notable growth throughout the period. While the cities showed the highest rate of having one child over the period , the rural areas accounted for the smallest figure. Futhermore, there was the biggest rate difference in the data of the single-families in the countryside compared with the other groups .
Examining the detail by three three regions over 20 years reveals that in 1980, the rate of single-child houses in cities showed the greatest number, with about 50%, followed by the outskirts, with 40% . In contrast, in the farmlands were responsible for the smallest firgue, with just 10%. The trends continued gradually growing between 1980 and 1990. The cities still presented both the most increasing by 45% in one child proportion, about 95% and the most enormous percentage difference of all regions compared with 10 years old. Whereas, the countryside had the least rate gap, by just 10%.
By the last decade ( 1990-2000) , the trends still changed significantly. The urban areas gave the highest rise and the rural areas had the lowest. On the other hand, the proportion of single-child households in the farmlands exhibited the biggest gap from 1990 to 2000, with 20% and 70% respectively.
