The graph below shows the percentage of part-time workers in each country of the United Kingdom in 1980 and 2010.

The bar chart illustrates the proportion of people engaged in part-time employment in the four countries of the United Kingdom—England, Wales, Scotland, and Northern Ireland—in 1980 and 2010.
Overall, there was a general rise in part-time employment across the UK over the 30-year period, with the exception of Northern Ireland. England and Wales consistently had higher percentages of part-time workers compared to Scotland and Northern Ireland.
In 1980, approximately 25% of the workforce in England was employed part time, a figure that rose to just over 30% by 2010. Wales recorded the highest proportion in both years, starting at around 33% in 1980 and increasing slightly to just above 35% in 2010.
Scotland had the lowest percentage in 1980, with just over 10% of workers in part-time roles. By 2010, this figure nearly doubled, reaching close to 20%. In contrast, Northern Ireland was the only region to experience a decline. While about 15% of its workforce held part-time jobs in 1980, this dropped marginally to around 13% by 2010.
