If you don't mind, I will answer in English.
I'm always struck by the need for evidence-based policy.
As the president of the Institute for Research on Public Policy, I would like to point out that many of our researchers base their research on the census and other surveys stemming from it.
If you think we should have policy-based evidence—that is, pick the policy and then go out and prove it—then you don't need a census.
If you want to base your policy on evidence, on the nature of the challenges that the country faces, on the nature of the problems of the performance of the economy, then you need the evidence first.
At the Institute for Research on Public Policy, we say that we ask questions before getting answers. I hope that the government does likewise.
