The graphs below give information about computer ownership as a percentage of the population between 2002 and 2010, and by level of education for the years 2002 and 2010.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The bar charts show data about computer ownership, with a further classification by(通过。。。的方式划分)level of education, from 2002 to 2010.
A steady but significant rise(平稳而显著的提升)can be seen in the percentage of the population that owned a computer over the period(在这个时段里). Just over half the population owned computers in 2002, whereas by 2010 three out of four(四个里面有三个=百分之75)people had a home computer.
An analysis of the data by level of education shows that higher levels of education correspond to (与。。。相对应)higher levels of computer ownership in both of those years. In 2002, only around 15% of those who did not finish high school had a computer but this figure had trebled(三倍)by 2010. There were also considerable increases, of approximately 30 percentage points, for those with a high school diploma or an unfinished college education (reaching 65% and 85% respectively(分别地;个别地)in 2010). However, graduates and postgraduates proved to have the greatest level of ownership in 2010, at 90% and 95% respectively, 20 percentage points higher than in 2002.
The last decade(过去的十年)has seen a substantial(很大程度的)growth in computer ownership in general, and across all educational levels(在各个。。。层面).
