NATIONAL INCOME AND PERSONAL INCOME: National income (NI) is the total income earned by the citizens of the national economy resulting from their ownership of resources used in the production during a given period of time, usually one year. Personal income (PI) is the total income received by the members of the domestic household sector, which may or may not be earned from productive activities during a given period of time. Personal income can be derived from national income by subtracting income earned but not received (IEBNR) and adding income received but not earned (IRBNE).
