Nobody will confirm that it's their reason but big family and low income ARE the grounds for receiving. Cut excess mouths, levy special tax on the 5th, 6th etc kid and you will see how it works.
Once more the Barroness did not speak about all immigrants but only Bangla+Pakistani with their huge families. The research do show that there are good immigrants like Poles and Indians, who follow different pattern.
