The chart gives us an overall picture of the changes in the ownership of houses. The first thing we notice is that state-owned houses’ ratio is diminishing and provite houses’ is increasing. This means that as time goes by, the proportion of occupied private houses is growing
We can see from the statistics given that state-owned house is 75% of total, which ratio was much higher than private houses’ in 1990. After 1990, the ratio on private house is increased as time. The figures also tells us that the increasing range on private house is much bigger in second 5 years than in first 5 years. In the second column of 2000, we can see that private house ratio accounts for 80% of total.
Judging from these figures, we can draw the conclusion that private purchase of house becomes more and more. The reason for this, as far as I am concerned is that people’s income increases much more. It is high time that we should develop the economical housing construction to meet more private needs.
