GDP (Gross Domestic Product) is the sum total of all goods and services produced in a country usually in one year. It is mentioned in monetary terms, usually in US dollars.

There is no such thing as GDP of education or poverty. What I have understood by your question is that, usually people describe the expenditure done on education or poverty in terms of GDP. So you can say that normally writers describe the importance of education or poverty to the government by describing how much government spends on education or poverty. The expenditure incurred is described in terms of the proportion of GDP.

The updated statistics on expenditure incurred on education or poverty can be had from Economic Survey of Pakistan, which is available on website of ministry of finance (www.mof.gov.pk).
