The given line graph illustrates the number of computers owned per household in one European country over a 14-year period, from 1997 to 2011.
Overall, the data shows an upward trend in the percentage of households owning computers, with the exception of those without computers, which saw a significant decline. Households with one computer consistently had the highest percentage, surpassing those with no computer at the beginning of the period. In contrast, the category of households with three or more computers remained at the lowest point throughout the entire period, despite a gradual increase.
In terms of specific trends, the percentages for households with three or more computers and those with two computers followed a similar pattern. In 1997, the percentage of households with three or more computers was negligible, remaining at zero until 1999. After that, it experienced a gradual increase, reaching around 7% by 2011. Meanwhile, the percentage of households with two computers started at approximately 8%, rising steadily to 20% in 2005. However, this figure dropped slightly to 19% in 2007, before increasing again to nearly 30% by 2011.
Regarding households with one computer, the percentage remained relatively stable throughout the period, starting at around 44% in 1997 and increasing marginally to 45% by 2011. On the other hand, the percentage of households without computers, which initially held the highest proportion, saw a dramatic decline over the period, dropping from about 48% in 1997 to approximately 20% by 2011.
