Is this what used to be called an ' impact assessment'?
'The impact of George Osborne’s changes to tax credits have been underlined by research that suggests two-thirds of working tax credit recipients will be worse off in 2020.
The findings were revealed as the House of Lords prepares to debate the changes – amid warnings from the government that it would provoke a constitutional crisis if peers voted to block the reforms.
The research conducted by Policy in Practice, a group that works with local authorities on welfare changes, is based on analysis of more than 100,000 households of working-age in receipt of housing benefit and council tax support, and also takes into account the impact of the national living wage at £9 an hour, and a personal tax allowance of £12,500.'
