Definition of Index

The Canada social science dictionary [1] provides the following meaning of Index: Many of the concepts social scientists study are quite complex and cannot adequately be measured by a single indicator. In these cases researchers develop several indicators and in some case will give different weights to each indicator. This combination of indicators and weights is an index. Socio-economic status is difficult to measure and typically the indicators of income, occupation and education are used. If occupation is seen as more central it may be given more weight. An index of socio-economic status is developed.
