There is a certain potential to analyze these questions through the census. As you know, the census is done every five years. The benefit of the census is that it can support very detailed research, but you're getting a signal every five years so it's difficult to assess changes over time or changes in response to specific policy interventions.
There are some limitations involved in that. We think that modernizing UCASS or enhancing UCASS, so that we can get a flow of these data every year for all institutions across the country, is likely to be the preferred option.
