The global GDP can be slit up between different sectors to see how sectors contributed to economical growth. I'm interested in knowing what elements are used to calculate the GDP in the real estate sector and which ones are the most important.
I understand the basic principles of how to calculate GDP, but I don't know how it applies to real estate sector.
Ideally I would like to be able to calculate an approximation of the GDP from official data about prices indices (for rent and sell), number of sells, number of housing constructions, number of people working in a real estate agency...
I'm interested in any information about this topic. If one can give a source to support their answer, that's great. (I'm not interested in a country in specific.)
Thank you !
