The charts depict the portion of employees in different sectors in the period from 2016 to 2020. Overall, both towns have seen a rise in the number of workers in the service sector, while the reverse was true for the manufacturing sector.

In town B, manufacturing, while experiencing a moderate decline from 70% to 53%, has maintained its status as the dominant sector. Over this period, the services sector skyrocketed, with its workforce proportion rising from 10% to 25%, while the sales sector saw a slight increase, gaining 2% and peaking at 22% in 2020.
