According to the chart, the citizens are being taxed

- Proportionally.

Explanation:

Tax is characterized as the amount charged by the government (on income, goods, or services) from the citizens for providing services like schools, hospitals, roads, trains, etc.

As per the question, the given chart reveals that the citizens are being taxed 'proportionally' which implies that a fixed percentage of tax similar for each income group i. e. 11% is levied upon them. Thus, the rate of interest remains same irrespective of the difference in income (high or low) which implies that the tax rate is in proportion to the income earned by individual.
