We measure and examine data error in health, education and income statistics used to construct the Human Development Index. We identify three sources of data error which are due to (i) data updating, (ii) formula revisions and (iii) thresholds to classify a country's development status. We propose a simple statistical framework to calculate country specific measures of data uncertainty and investigate how data error biases rank assignments. We find that up to 34% of countries are misclassified… 

Misclassification Bias in Computational Social Science: A Simulation Approach for Assessing the Impact of Classification Errors on Social Indicators Research

A simulation approach for assessing the impact of misclassification bias on the calculated social indicators in terms of regression and correlation metrics and allows for assessment of the optimistic level of correlation between the indicator calculated based on the results of the classification algorithm and the true underlying indicator.

Classifying Human Development with Latent Class Analysis

We use latent class analysis to create an indicator of human development that integrates a broad range of country characteristics including per capita income, health, inequality, environmental

The Quality of Growth

We use latent class analysis to categorize development experiences. This technique allows us to consider a broad range of country characteristics including per capita income growth, health,

Using Spatial Factor Analysis to Measure Human Development

We propose a Bayesian factor analysis model as an alternative to the Human Development Index (HDI). Our model provides methodology which can either augment or build additional indices. In addition to

Multidimensional Poverty Measurement and Analysis: Chapter 8 – Robustness Analysis and Statistical Inference

This chapter shows how to apply dominance and rank robustness tests to assess comparisons as poverty cutoffs and other parameters changes, and presents ingredients of statistical inference, including standard errors, confidence intervals, and hypothesis tests.

The Analysis of Human Development Index (HDI) for Categorizing the Member States of the United Nations (UN)

Data that reflect the measures of life expectancy index (LEI), education index (EI), and income index (II) are analyzed to categorize and to rank the member states of the UN using R statistical software package, an open source extensible programming language for statistical computing and graphics.

How robust are composite indicators? An almost certain stochastic simulation approach

Stochastic techniques such as Monte Carlo simulations are widely used to investigate complex empirical problems. In particular, they can be used to quantify the sensitivity of composite indicators to

HDI: The Old, the New and the Elegant

This paper evaluates three aggregation methods of computing HDI using a set of axioms and proposes an alternative measure, where HDI is the additive inverse of the distance from the ideal.

Making Data Measurement Errors Transparent: The Case of the IMF

In 1950 Morgenstern pointed out that absolute precision and certainty are impossible in economic observations, but estimates are often hampered by a substantial degree of measurement error. Unlike

Assessing the Effects of Various Socio-Economic and Health Indicators on HDI Country Categories

The human development indicator (HDI) is based on three indicators: standard of living, life expectancy, and education level. Although being widely known and commonly used, the accuracy of the HDI



Disease and Development: The Effect of Life Expectancy on Economic Growth

We exploit the major international health improvements from the 1940s to estimate the effect of life expectancy on economic performance. We construct predicted mortality using preintervention

The Human Development Index: "Handle with Care"

ECONOMISTS AND POLICYMAKERS have long questioned the emphasis on growth of gross national product per capita (GNP/N) as the singular goal and measure of national development. GNP/N fails to capture

The human development index: some technical issues and alternative indices

This paper examines the components and structure of the UNDP's Human Development Index and briefly reviews the criticisms of this index in the literature. It suggests some improvements on the

Human Capital in Growth Regressions: How Much Difference Does Data Quality Make?

We construct a revised version of the Barro and Lee (1996) data set for a sample of OECD countries using previously unexploited sources and following a heuristic approach to obtain plausible time

International Data on Educational Attainment Updates and Implications

This paper presents a data set that improves the measurement of educational attainment for a broad group of countries. We extend our previous estimates of educational attainment for the population

human Development Index

How many countries are included in the 2013 HDI? The 2013 HDI covers 187 countries, the same number as in 2012 and 2011. Maintaining the same number of is the result of intensified efforts by the

An empirical note on inequality in the world development indicators

A broad range of inequality measures is used to examine inter-country inequality in two highly correlated indicators of development, the per capita real income (Y) and the Human Development Index

Human development:Concepts and measurement

The Income Component of the Human Development Index

Focuses on 'The Human Development Reports' of the United Nations Development Programme, that attempts to take on the task of incorporating the view of human beings as ends in the accounting and
