I want a data source where I can get all of the following from 1973 to present:

GDP per capita (PPP)
Ag and Non Ag value added (so Ag and Non Ag output)
Employment data in Ag and Non ag


I was able to get the last 2 from WDI but they only have PPP from 1980 onward. I know PPP started at that time, but other sources have estimates going back further. I can't use PWT because they do not break down GDP by sector for me to get the Ag and Non Ag.

It is ok for me to get the employment data from a separate source, so I essentially need to find GDP per capita (PPP) and Ag/NonAg value added from the same source.

I couldn't find the Ag/NonAg at OECD.

Thanks.
