Do Parents Drive More Than People Without Kids?

01 Introduction

"Parents drive more" sounds like it should be true almost by definition: school runs, activities, errands for a household that suddenly has more people and more places to be. The 2022 National Household Travel Survey classifies every household by life-cycle stage, including the age of the youngest child present, which makes it possible to actually test that assumption stage by stage rather than accepting it as an average across every parent regardless of their child's age. The real pattern turns out to be far more specific, and far more interesting, than a flat "yes."

02 A Naive Comparison Would Mislead You

The most obvious way to run this comparison is also the wrong way: averaging daily driving miles across every person in a household, children included. Since a household's youngest child obviously doesn't drive, counting that child as a "0 miles driven" person mechanically drags down the household average for any family with young kids, regardless of how much the actual adults drive. Restricting the comparison to adults (age 18 and older) removes that artifact and changes the picture substantially.

Including young children in the average makes it look like households with kids under 16 drive dramatically less across the board. Once the comparison is restricted to the adults actually doing the driving, the households with a youngest child 6–15 flip from "driving less" to "driving 10% more" than childless adults. Every figure in the rest of this article uses the adults-only comparison.

03 The Real Pattern: Miles by Household Life Stage

With that correction in place, adult driving mileage traces a clear arc across the parenting years: a dip when children are very young, then a steady climb that peaks when the youngest child is a teenager, before falling off in retirement.

Parents of infants and toddlers are the only parent group that drives less than childless working-age adults, plausibly reflecting reduced work hours or one parent staying closer to home during a child's earliest years. From there, adult driving rises with the child's age, overtaking the childless baseline once the youngest child is school-age and peaking when that child is a teenager, before the household eventually returns to a lower-mileage retirement phase.

04 The Proof: Chauffeuring Trips Rise, Then Vanish

A miles-only comparison can't say why parental driving rises and falls the way it does. The trip-purpose data can. Looking specifically at the share of adult personal-vehicle trips made for the purpose "transport someone" (code 70 in the survey, essentially chauffeuring another person), the pattern lines up almost exactly with the mileage curve above, and explains the confusing part of it: why the youngest-child 16–21 group has the highest mileage but doesn't show the same chauffeuring spike as younger-kid households.

Parents of children under 16 spend roughly three times the share of their driving trips shuttling someone else around, exactly the "school run and activities" pattern the introduction's naive assumption predicted, just concentrated in a specific age window rather than spread evenly across all parents. Once the youngest child turns 16 and can plausibly drive themselves, that chauffeuring share drops right back to the childless-adult level, even though total household mileage is still at its highest point in the entire table.

05 Why the Teen-Years Peak Happens

NHTS doesn't ask households to explain this directly, so this section is this site's own interpretation of the two tables above, not a separately published government finding. The note in Section 01 matters most here: the 16–21 group's combination of highest mileage and lowest chauffeuring share is best explained by that same overlap, an 18-to-21-year-old counted as an "adult" in this article's analysis while still being the household's "youngest child" by NHTS's own relationship-based definition. That overlap explains both halves of the pattern at once: parents are no longer chauffeuring as much, because the now-adult child drives their own car to their own destinations, yet the household's total adult mileage keeps climbing, because there's simply one more independent driver, with their own commute, social life, and errands, now counted in the average.

06 What This Means

The honest answer to "do parents drive more" is: it depends entirely on how old the kids are, and averaging across all parents would hide a real, three-phase pattern. New parents of infants and toddlers can reasonably expect to drive less, not more, at least in terms of raw miles, even as a larger share of what driving they do becomes chauffeuring-related. Parents of school-age and teenage children should expect a genuine, measurable increase in their own driving, peaking almost 20% above a childless adult's baseline right as their child approaches driving age. And once a teenager starts driving independently, the household's overall mileage doesn't fall, since the family gains a whole new driver, even though any individual parent may finally be chauffeuring less than at any point since the child was born.
