A team of public health researchers studies mosquito populations in neighborhoods in Baltimore, looking for correlation between socioeconomic status and mosquitoes.
They concluded that while richer people had more lavish gardens -- in which mosquitoes found places to breed during dry periods -- that mosquitoes really found fertile breeding grounds in poor neighborhoods, thanks to higher levels of abandoned buildings and cars where water could pool when there was rain.
We demonstrate that both precipitation and vegetation influence mosquito production in ways that are mediated by the level of infrastructural decay on a given block. Mosquitoes were more common on blocks with greater abandonment, but when precipitation was low, mosquitoes were more likely to be found in higher-income neighborhoods with managed container habitat. Likewise, although increased vegetation was a negative predictor of mosquito infestation, more vegetation on blocks with high abandonment was associated with the largest mosquito populations. These findings indicate that fine spatial scale modeling of mosquito habitat within urban areas is needed to more accurately target vector control.

China's move into a "mixed economy" has created a wealth inequality crisis to rival any nation's; wildcat workers' strikes (aided by Young Communist movements) have become increasingly common, though they are not often reported in the news (it helps that Chinese state media and the country's official censors suppress these reports).
The Trump administration is very proud of the US's historically low unemployment figures (lowest in 50 years), but statistics are deceiving, especially labor statistics.
114,659 of New York's public school students is homeless, bouncing from shelters to relatives' beds: homelessness is a predictor of poor academic performance for all the obvious reasons, including very long commutes to school (some students' families have ended up at shelters that are two boroughs away from their schools).
