- Methodological explanations

- In the reference years 2008, 2009 and 2010 some enterprises that carry out R&D activity and had previously not been part of the reporting of R&D data were included in the business enterprise sector.
- The survey on R&D activities in the reference year 2011 was based on new administrative sources, which enabled us to further identify R&D companies/organizations to improve the capture of units in the sample. Thus, the higher value of data on total spending on R&D was in addition to investment in this activity also the result of the expanded selection of reporting units, primarily in the business enterprise sector, and moving of some borderline respondents from the government sector to the business enterprise sector. At the same time, with the reference year 2011 we improved the analysis of non-response, which also helped increase the value of all published statistics in all sectors. This resulted in the break in time series.
- Totals are not always accurate due to rounding.
