NOTE: Data files beginning with calendar year 2005 are now available as downloads. The download format for years 2005 through 2009 is CSV (Comma Separated Values): A data format in which each piece of data is separated by a comma. This is a popular format for transferring data from one application to another, because most database and spreadsheet systems are able to import and export comma-delimited data. CSV files can be opened by the majority of spreadsheet and database programs available. If opened in Excel, column widths will have to be adjusted. The data files beginning with calendar year 2010 onward are in Excel.
