Federal expenditures on science and technology and its components, by activity and performing sector - Intentions (x 1,000,000)^{1 2 3}

Due to rounding, components may not add to the totals.

Conceptual changes were implemented for the 2016/2017 survey cycle to account for non-program costs (indirect costs). The value of services provided without charge to the responding department by other federal government departments will not be added. Revisions were applied to data on intramural expenditures and related activities back to 2010/2011. These revisions affect expenditure totals by type of science, science and technology, research and development, and related scientific activity. As a result, data for 2010/2011 onward are not comparable with data for previous years.

The last two years of data in this table represent preliminary estimates and intentions, reported at the time of data collection.

Starting with 2016/2017 data, intramural research and development (R&D) 'Supporting Contracts' and R&D contracts for intramural expenditures that have been removed and are included with 'In-house R&D'.

Starting with 2016/2017 data, the 4 related scientific activity (RSA) sub-categories of 'Scientific/General purpose data collection', 'Information services', 'Special services and studies' and 'Education support' have been removed. These are replaced by the same 3 categories found in the research and development (R&D) section: 'In-house RSA', 'RSA Contracts' and 'RSA grants and contributions'.
