# Percentiles

A percentile defines a fraction or subset of papers in a research field that have received a minimum number of citations. The smaller the percentile, the higher the minimum number of citations. Percentile values are baselines for evaluating research impact. For example, if the value of the 1.00% percentile is 15, a paper in the same research field in the same year must receive at least 15 citations to belong to that percentile.

## Sample Report

The following sample from a Percentiles table reveals that papers from 2011 that received at least 14 citations fall in the 10% percentile of papers in Microbiology. It follows that 90% of Microbiology papers published in 2011 received fewer than 14 citations.

For all years, Microbiology papers in the 10% percentile received a minimum of 38 citations.
