There is more poverty in Wales' working households than in those where no one has a job.
The findings, by the Joseph Rowntree Foundation, blame a low pay job market.
Currently 690,000 people in Wales are classed as living in poverty - those who have less than 60 per cent of the average income.
That's almost a quarter of the population here - a higher rate than the other countries in the UK - and worst in rural areas.
Furthermore, 285,000 people - half of those classed as in poverty - are struggling despite having a job.
