Canyon of Heroes: After the U.S. women’s national soccer team won the World Cup, New York honored the women with a ticker-tape parade last week. This chart shows us the spirited history of those who’ve earned ticker-tape parades in New York, dating to the 1910s. From celebrating world leaders to “adventurers,” there have been some curious reasons for ticker-tape parades. (See: Douglas “Wrong Way” Corrigan in 1938.) [Noah Veltman]

Experiments in birth control: After a six-year, statewide initiative, Colorado saw a surge in the number of young women using long-acting birth control, especially in the poorest parts of the state. Records indicate that one-fifth of women aged 18 to 44 in Colorado are now using long-acting contraception. Even more striking: the birthrate and rate of abortions among teenagers dropped by 40 and 42 percent, respectively, from 2009 to 2013. [The New York Times]

Seventy-nine percent of elected state and local prosecutors were white men in 2014. [The New York Times]
