It would be related to all of the factors that I stated within the presentation, so part-time work, labour market segmentation, inability to work at all because of lack of supports and education, but also all of the other social issues that affect indigenous communities.

So why women more than men? It's for all the same reasons other women as well are lower in the wage gap than men. I'm not sure it's as precise, but racism also would play into it. It's not a terribly precise answer to your question but it would be that all of the different social issues have claim to it.
