Shortcomings of GDP ?

1.GDP only counts activity that happens inside the money economy. Many of the most important types of economic activity (including food production, education, raising children, even transportation) happen both inside and outside the money economy, and these are not included in GDP. 2. GDP aggregates figures based on price, not value. Sales of the same goods or services at a higher price contribute more to GDP, even though they contribute equally to the wealth available in a country. 3. GDP measures only production, and does not measure the destruction, loss, or using up, or squandering of wealth or resources. GDP is thus measuring only "half the equation" (less than half when considering the first point above) when it comes to what is affecting the total amount of wealth in a country. 4. Per-capita GDP measures only average prosperity and does not address disparities in wealth, income, and resource distribution.
