Context: The list below represents a national accounts derived indicator for a country or territory's gross household disposable income per capita (including social transfers in kind). According to the OECD, 'household disposable income is income available to households such as wages and salaries, income from self-employment and unincorporated enterprises, income from pensions and other social benefits, and income from financial investments (less any payments of tax, social insurance contributions and interest on financial liabilities). 'Gross’ means that depreciation costs are not subtracted.' This indicator also takes account of social transfers in kind 'such as health or education provided for free or at reduced prices by governments and not-for-profit organisations.' The data shown below is published by the OECD and is presented in purchasing power parity (PPP) in order to adjust for price differences between countries.


Question: Extract the difference between Gross Disposable income from Disposable Income


assistant
There is a unique difference between Gross Disposable Income and Household disposable income.  The first being that "gross" indicates the total about amount of income derived from all sources such as wages, investments, self-employment, pensions and social benefits before extracting depreciation costs.  Household disposable income includes all sources of income less social benefits, taxes, insurance, and liabilities such as rent, electricity and other ongoing financial commitments.  What is remaining is defined as household disposable income which is then indexed globally using PPP (purchasing power parity) in order to adjust for price differences in different countries.
