Yes, Mexico (and every country) should strive to get an accurate count. If it knows more precisely how many of its people are living in poverty, then the Mexican government can adopt policies that will better help its most disadvantaged members of the population. People in Mexico who need help should get it.
The measurement of absolute progress is a worthy undertaking, but in terms of evaluating the lived experience of poverty and its detrimental effects, it is equally important, if not more so, to explore the relative progress of the poor. The semi-success of government anti-poverty policy has also marginalized and beaten down millions of people. Without understanding relative poverty — and in particular the “small percentage” that falls to the very bottom, almost off the grid — they haven’t really begun to tackle the problem.
Mexico is changing the way it measures family income in an attempt to get Mexicans to report every little bit of their earnings. Now, after a recent survey, the government knows that most household incomes were nearly 33 percent higher than previously thought. This new method, which involves interviewers digging a little deeper with their questions, is a much more effective way of finding the household's total earnings than the one previously used.
The problem of poverty is one that every nation faces and should take strong measures to combat. By changing the way they measure their poor's wealth, Mexico is just ignoring the problem and pretending the steps they have taken are actually helping those in need. Mexico should face reality and implement real programs to help the poor, instead of pretending they are currently helping.
