INSP {Relectoral}

Nationalisation Index of the Political Party System (INSP)

Description

This indicator is based on the nationalization index of each party. Its calculation is computed using the aggregation of party nationalisation scores weighted with the value of electoral weight, that is, the number of votes obtained. As with the Party Nationalisation Index (INP), values close to 1 will indicate strong nationalisation and values close to zero will indicate the opposite. The formula used for this indicator is as follows:

INSP=sum(INPi x pi)

Where INPi is the nationalization index of party i, and pi is the number of votes obtained by party i.

Usage
