Last week, MetroTrends bloggers offered up solid information about perennial challenges vexing public policymakers in US metros:

• Barbara Ormond ponders what it what it will take to change Americans’ eating habits.
• John Roman offers compelling evidence of declining crime rates in big cities nationwide.
• Molly Scott warns that poverty among Latino kids may be even higher than the latest estimates suggest because so many of their families are doubling to cut housing costs.
• And Greg Mills argues that policy researchers shouldn’t launch randomized control trials until they’ve worked the bugs out of program designs.

See you again next week.
