UPenn is definitely very strong for urban analytics, especially with the MUSA program also housed within Weitzman. Then again, iirc Harvard lets you take almost half your classes at MIT which is arguably even better for smart cities and analytics (and does some amazing work at the intersection of analytics and housing, if that’s your interest).
Personally I’m probably going to UPenn but if I had applied and been accepted to Harvard, I probably would’ve gone there instead. That’s partly because my interests lean more towards design though. What are your specific areas of interest within HCED?
