1. Determine the value of one grid subdivision on the vertical axis

The interval from 00 to 300300 is divided into 66 equal subdivisions.
Value of one subdivision = 300÷6=50300 \div 6 = 50 members.

2. Read the value for the year 2020

The bar for 2020 is 33 grid lines above the 600600 mark.
Number of members in 2020 = 600+3×50=600+150=750600 + 3 \times 50 = 600 + 150 = 750.
