Fast Radio Bursts (FRBs) are classified into repeaters and non-repeaters,with only a few percent of the observed FRB population from the CanadianHydrogen Intensity Mapping Experiment (CHIME) confirmed as repeaters. However,this figure represents only a lower limit due to the observational biases, andthe true fraction of repeaters remains unknown. Correcting for these biasesuncovers a notable decline in apparently non-repeating FRB detection rate asthe CHIME operational time increases. This finding suggests that a significantportion of apparently non-repeating FRBs could in fact exhibit repetition whenobserved over more extended periods. A simple population model infers that thetrue repeater fraction likely exceeds 50% with 99% confidence, a figuresubstantially larger than the observed face value, even consistent with 100%.This greater prevalence of repeaters had previously gone unnoticed due to theirvery low repetition rates ($\sim$10$^{-3.5}$ hr$^{-1}$ on average). Hence,theoretical FRB models must incorporate these low-rate repeaters. Furthermore,our results indicate a significantly higher repeater volume number density,potentially exceeding observed values by up to 10$^4$ times, which in turnimpacts comparisons with potential FRB progenitors.
