Additional measures like the decile ratio (share of the 90th percentile/share of the 10th percentile) and the coefficient of variation are also popular ways of measuring dispersion in the distribution. Analysing the entire distribution has a number of advantages and allows the analyst to identify whether changes in inequality are due to changes in the welfare of individuals at the top or the bottom of the income distribution. Additionally, looking at the entire distribution makes it easier to relate growth, inequality and poverty to each other.
