The pie charts present data on the percentages of the residents in two towns working in three distinct sectors. Overall, each town displayed a unique pattern of job distribution in both years.
In town A, the proportion of people working in the manufacturing industry increased from 29% in 1960 to 64% in 2010, representing the dominant sector then. Nevertheless, other sectors experienced a reduction in the workforce, for example, the percentage of employees in sales was 41% in 1960 and decreased to 20% in 2010. Similarly, 30% of the town residents worked at services, but declined to 16% in 2010.
Despite a reduction of 17%, the most prevalent sector was consistently sales in town B. Approximately 10% of the people were in the manufacturing business, but this figure grew to 25% in 2010. At the same time, the number of employees at sales increased by 2%.
The graphs compare different sectors in which people worked. Notably, sales was the most popular sector in 1960, while in 2010, it was manufacturing. In contrast, in town B, the majority of people worked in sales in both years.
