“In England’s residential nurseries in the 1960s, there was a reasonable number of caregivers, and the children were materially well provided for.

Usually "more recently" implies a comparison between two recent events but here we are talking about something that happened more than half a century ago so I wonder if "more recently" just means "recently here. Thanks!
