### Comment:
I mean if you feel that strongly you could just read the actual study. Obviously in developed nations it’s not as big a deal, but it seems like a great indicator for objectively judging growth in emerging markets. Especially in Asian countries where night markets are a huge part of the culture.

### REPLY:
Look at it the other way around. A growth in nighttime lights might indicate a growth in GDP, but a growth in GDP does NOT indicate a growth of nighttime lights.   
  
 If China's GDP jumped up massively due to some rich companies making more money due to exports, this wouldn't trickle down to dirt poor rice farmers at all.

### END.
