For about 20% of the combinations of industry, location, and company size, our partner for the LivePlan benchmarks data, Abrigo, could not provide the 3-year-average benchmark data. We chose the best data provider available for these statistics, but even their data isn't complete for all industries when the selections become very granular. In these cases, they've provided 10-year-average benchmark data to us instead.
If you want to see 3-year-average data for your industry, try switching to another region (or selecting the entire US) or choosing a larger company size. This may widen out the search enough to give you 3-year-average data.
