The Parkland school shooting has had a lasting effect on U.S. teenagers, with most now worried a shooting could happen at their school, according to a survey released today by the Pew Research Center.

Between the lines: If you dive deeper into the numbers, you'll find that teenagers and parents of different backgrounds have different levels of anxiety about gun violence at their schools.

• Overall, 57% of teenagers are worried about a shooting at their school.
• But African-American and Hispanic teenagers are more worried than white teenagers — with more than two thirds of Hispanic teenagers expressing fears.
• Girls are more worried than boys.
• 63% of all parents are concerned.
• But low-income parents are the most worried — 82% of parents with incomes under $30,000, compared to 53% of parents with incomes over $75,000.

The bottom line: Parkland has left a terrible legacy of anxiety among teenagers and their parents — but the survey also shows how much our backgrounds and life experiences can affect how we view school violence.
