Black people in criminal courts in Canada: An exploration using the relative rate index

There is an image of a flow chart designed to look like an equation. There are three vertical columns. On the left side, there are four boxes. The top two boxes in the left column read:

1. Number of Black people experiencing the outcome
2. Number of Black people at risk of experiencing the outcome

To the right of the top left boxes, there is an equal sign leading to a box in the middle column that reads: Rate of Black people experiencing the outcome

There is a thick black line like the dividing line in a fraction.
Below this line, there are two boxes in the bottom left column that read:

1. Number of White people experiencing the outcome
2. Number of White people at risk of experiencing the outcome

To the right of the bottom left boxes, there is an equal sign leading to a box in the middle column that reads: Rate of White people experiencing the outcome

To the right of the two boxes in the middle column, there is an equal sign leading to a box in the right column that reads: Relative Rate Index

There is an arrow from this box that leads to a text box below the equation that reads: Lesser chance of experience the outcome (-%) < 1 (0% ) > Greater chance of experiencing the outcome (+%)
