It refers to family consisting of at least one nuclear family with other non-relatives.

A composite household is a household consisting of any of the following: a single family nucleus plus other persons, some of whom are related to the nucleus and some of whom are not, for example, mother with child(ren) and other relatives and non-relatives; a single family nucleus plus other persons, none of whom are related to the nucleus, for example, father with child(ren) and non-relatives; two or more family nuclei related to each other plus other persons, some of whom are related to at least one of the nuclei and some of whom are not related to any of the nuclei, for example, two or more couples with other relatives and non-relatives only; two or more family nuclei related to each other plus other persons, none of whom are related to any of the nuclei, for example, two or more married couples one or more of which with child(ren) and non-relatives; two or more family nuclei not related to each other, with or without any other persons; two or more persons related to each other but none of whom constitute a family nucleus, plus other unrelated persons; non-related persons only.

A composite leading indicator (CLI) is an aggregate time series displaying a reasonably consistent leading relationship with the reference series for the macroeconomic cycle in a country.

Component series of the OECD composite leading indicator (CLI) are equally weighted in the aggregation process into a country CLI. On the other hand, GDP-PPP weights are used to estimate the CLIs for groups of countries, i.e. zone.

 It is formed from materials of concrete and iron.

A technique for using computers to help with one or more phases of the software life-cycle, including the systematic analysis, design, implementation and maintenance of software. Adopting the CASE approach to building and maintaining systems involves software tools and training for the developers who will use them.
