Moreover, unlike economic development which can be measured quite precisely in terms of rising per-capita income,
or social development which can also be measured fairly precisely as rising literacy, rising urbanization, and rising life expectancy, political development is far more difficult to measure. How do we know when a country is politically developed? Especially when, as previously noted, there are so many definitions of development? What criteria would we use, and what measures? Is it when a country is democratic, and how precisely do we measure that when it has developed political parties, interest groups, and government agencies? If we look back at Tables 1.1 and 1.2, we see that economic and social development can be measured with the use of several criteria but there is not a single gauge for political development. These definition and measurement problems would continue to plague the political development approach
