The Base Effect is a concept where there is a mathematical distortion in comparing numbers where the base is either extremely high or low. We can see this happening during periods of rare economic events such as 2020 (shout out to global pandemics, business closures, panic buying, wildfires, etc.), as the base of year over year calculations. When we look at this graph, we see that the YoY growth rates in 2019 when compared to 2018 were relatively stable (i.e., the blue line), but the jumps in growth comparing 2020 to 2019 were 3x to 4x larger. So what? This means we have a HUGE base of sales in 2020, so we need to be particularly mindful of what we are working with when looking at YoY comps during 2021.
