FTE: Full-time equivalent 
 The years 1994, 1996 and 1998 are estimates.   
 The data for the years 2001(*) onwards include continuous and occasional R&D. 
 As of 1995, the PNP sector is included in 'Total personnel' and 'Researchers'
 Since 2013 (**): Population base change in EPA estimates.

 '...'= data not available 
 '.'=numeric data equal to zero not resulting from rounding 
~'indicator type,Total personnel: Persons in FTE (per thousand with respect to the employed population)'~Until 2002, the percentage per thousand was calculated with respect to the Active Population
~'indicator type,Researchers: Researchers at FTE (so much per thousand with respect to the employed population)'~Until 2002, the percentage per thousand was calculated with respect to the Active Population
