Turns out, it correlates with how many kids you have.

In a fascinating new survey conducted by Safehome, a company dedicated to reviewing security systems, 1,000 Americans across the country opened up about how often they really lock their front door. According to the results, some areas of the country are more likely to play it safe than others. While 81% of respondents in the Southeast said they lock their door, only 54% in the Northwest reported doing so.

Why the disparity between these two regions? According to Safehome’s analysis, these results may reflect the likelihood of a burglary in these various areas. In 2015, the South had the most burglaries in the country, accounting for 45% of total burglaries, which could be the reason why more Southerners lock their doors. Then again, although the Northeast was home to just 10% of burglaries in 2015, 58% of respondents in New England and 74% in the Middle Atlantic said they lock their doors—showing that respondents were cautious even when the chance of burglary was lower. Better safe than sorry, right?

In addition to looking at the results by region, the survey also analyzed them by type of housing, how well people know their neighbors, which other safety features people used (those with large dogs lock up the least!), and how many children people have. Interestingly, after their first child, respondents with more kids were less likely to lock the door. While 80% of households with one child locked up, only 54% of households with four or more kids did so. Between rushing out the door in the morning and convincing your teen to remember to lock the house before heading to school, it’s no wonder larger families tend to forget this simple safety move.
