Explain how 'distribution of Gross- Domestic Product'

Explain how ‘distribution of Gross- Domestic Product’ is a limitation in taking Gross Domestic Product as an index of welfare.

If the Gross Domestic Product of a country is rising sharply, it may not necessarily indicate welfare. This is because the rise in GDP may be concentrated in the hands of very few individuals or firms.
It means the gap between the rich and poor is widening due to these inequalities in the distribution of income. It means welfare of the common people does not rise with the rise in GDP.
