Hello, The Human Feb. 2009 (hg19) assembly includes chr1 of length 249,250,621 The Human Mar. 2006 (hg18) assembly includes chr1of length 247,249,719
When a file is downloaded (from the Table Browser, Downloads server, or ftp), the database version is one of the variables in the html form, url, or file path. We recently added the hg19 assembly to the UCSC Browser. The hg18 assembly is still the "default" for Human in forms/links while we finalize the hg19 major tracks. Confirming that all data is from the same assembly version should correct the data/version discrepancy you describe.
