Development Indices and PingER

 Introduction

Classifying countries by their development is difficult. One has to determine what to measure that is related to development and then measure it. There are then costs and practicality concerning: what can be measured, how useful it is, how pervasive it is, how well defined it is, how it changes over time, whether one is measuring the same thing for each country, and the cost of measuring. Various organizations such as the ITU, UNDP, CIA, World Bank etc. have come up with Indices  based on measured items such as life expectancy, GDP, literacy, phone lines, Internet penetration etc. (see below). These measures take time to gather and so are often dated and only available, if at all,  at widely separated intervals.

Another approach is to look at measures of the Internet that can be gathered automatically without running surveys, which in turn can be ambiguous. For example the work of Tom Vest of CAIDA comparing the numbers of Autonomous System Numbers (ASN's) related to Internet deployment using BGP for the measurement data (also see Internet Traffic Exchange: Market Development and Measurement of Growth from the OECD) . The PingER project has also been gathering end-to-end Internet performance measurements since 1995 and currently measures the performance of over 125 countries. This document outlines various of the survey based Index classification methods and then goes on to compare them with each other and the PingER measurements.

Gross Domestic Product per capita

The gross domestic product or GDP is a way of measuring the size of a region's economy. It is usually normalized by dividing by capita. It is often compared with the purchasing power parity (PPP) of the currency relative to the US$. There are measures from the World Bank and the Central Intelligence Agency among others,

Human Development Index (HDI)

The UNDP  Human Development Index  report of 2006 was compiled on data from 2004 and covered 175 UN member countries (out of 192). It is a comparative measure of life expectancy, literacy, education, and standards of living for countries worldwide. More specifically:

• A long and healthy life, as measured by life expectancy at birth
• Knowledge, as measured by the adult literacy rate (with two-thirds weight) and the combined primary, secondary and tertiary gross enrollment ratio (with one-third weight)
• A decent standard of living, as measured by GDP per capita (PPP US$).

It is a standard means of measuring well-being, especially child welfare. It is used to distinguish whether the country is a developed, a developing, or an under-developed country, and also to measure the impact of economic policies on quality of life. The index was developed in 1990 by Pakistani economist Mahbub ul Haq.

Digital Access Index (DAI) 

The Digital Access Index (DAI) from the ITU has data from  1995   to 2003. It combines eight variables, covering five areas, to provide an overall country score. The areas are availability of infrastructure, afordability of access, educational level, quality of ICT services, and Internet usage. The results of the Index point to potential stumbling blocks in ICT adoption and can help countries identify their relative strengths and weaknesses.

Digital Opportunity Index (DOI)

In 2006 the ITU submitted the Digital Opportunity Index report for 180 economies worldwide. The Index monitors the mobile communications that promise to bridge the digital divide in many parts of the world, as well as more recent technologies such as broadband and mobile Internet access.

Network Readiness Index (NRI)

The Network Readiness Index (NRI) was used in the World Economic Forum's Global Information Technology Report 2007-2007. It covers about 120 countries. It rests on three main subindexes:

• the presence of an ICT-conducive environment in a given country by assessing a number of features of the broad business environment, some regulatory aspects, and the soft and hard infrastructure for ICT;
• the level of ICT readiness and propensity of the three main national stakeholders---individuals, the business sector, and the government; and
• the actual use of ICT by the above three stakeholders.

Technology Achievement Index (TAI)

The United Nations Development Programme (UNDP) introduced the Technology Achievement Index (TAI) in 2001 to reflects a country's capacity to participate in the technological innovations of the network age. It contains data from 1995-1000 andf covers 72 countries. The TAI aims to capture how well a country is creating and diffusing technology and building a human skill base. It includes the following dimensions: Creation of technology (e.g. patents, royalty receipts); diffusion of recent innovations (Internet hosts/capita, high & medium tech exports as share of all exports); Diffusion of old innovations (log phones/capita, log of electric consumption/capita); Human skills (mean years of schooling, gross enrollment in tertiary level in science, math & engineering).
