GenBank and WGS Statistics

Notes on GenBank statistics

The following table lists the number of bases and the number of sequence records in each release of GenBank, beginning with Release 3 in 1982. CON-division records are not represented in these statistics: because they are constructed from the non-CON records in the database, their inclusion here would be a form of double-counting. From 1982 to the present, the number of bases in GenBank has doubled approximately every 18 months.

Notes on WGS statistics

The following table lists the number of bases and the number of sequence records for WGS sequences processed at GenBank, beginning with Release 129.0 in April of 2002. Please note that WGS data are not distributed in conjunction with GenBank releases. Rather, per-project data files are continuously available in the WGS areas of the NCBI FTP site: ftp://ftp.ncbi.nih.gov/ncbi-asn1/wgs ftp://ftp.ncbi.nih.gov/genbank/wgs
