There are a couple of recent surveys of CNVs from genome sequencing projects:
Abel, H.J. et al.Mapping and characterization of structural variation in 17,795 human genomes. Nature (2020).
Collins, R.L. et al.A structural variation reference for medical and population genetics. Nature 581, 444-451 (2020).
Also the 1000 Genomes paper: Sudmant, P.H. et al.An integrated map of structural variation in 2,504 human genomes. Nature 526(2015).
If you have array data PennCNV is the most commonly used method or you could use my CamCNV method (Article Detecting rare copy number variants from Illumina genotyping...
