Amid growing controversy about the oft-cited “30-million-word gap,” this investigation uses language data
from five American communities across the socioeconomic spectrum to test, for the first time, Hart and Ris-
ley’s (1995) claim that poor children hear 30 million fewer words than their middle-class counterparts during
the early years of life. The five studies combined ethnographic fieldwork with longitudinal home observations
of 42 children (18–48 months) interacting with family members in everyday life contexts. Results do not sup-
port Hart and Risley’s claim, reveal substantial variation in vocabulary environments within each socioeco-
nomic stratum, and suggest that definitions of verbal environments that exclude multiple caregivers and
bystander talk disproportionately underestimate the number of words to which low-income children are
exposed.
Recently, considerable attention has been paid to
the disparity in the number of words spoken to
very young children from socioeconomically disad-
vantaged families compared with their privileged
peers. Although this relationship has been oft
noted, the current reiterations of the argument her-
ald the 30-million “Word Gap,” citing Hart and Ris-
ley’s (HR) study of 42 Kansas families conducted in
the 1980s (Hart & Risley, 1995, 2003). HR calculated
the mean number of words spoken to each child
across 1-hr monthly observations from the child’s
first to third birthday. HR then extrapolated from
this average to predict the number of words the
child would hear in the first 4 years of life. In this
manner, HR estimated that the children in their
most impoverished group (six African Americans)
heard 30 million fewer words than did the children
in the most privileged group (13 offspring of
professional families, one of whom was African
American). These findings have never been repli-
cated.
The Word Gap has garnered widespread atten-
tion beyond the academy. Media interest acceler-
ated in 2013 when the Bloomberg Philanthropies
Mayor’s Challenge awarded Providence, RI its
grand prize to “Providence Talks.” This project pro-
posed to teach poor parents how to speak to their
children with the aid of an electronic device that
measured their words. Another prominent example
is the Clinton Foundation’s Too Small to Fail Initia-
tive, which hosted the White House Word Gap
Event in October 2014. Initiatives announced at this
policy forum included potential funding by the U.S.
Department of Health and Human Services for
remedial efforts to address the Word Gap. Recent
attention includes an Associated Press report on the
Providence initiative that was picked up by major
news outlets including the New York Times (Neer-
gaard, 2017).
Not all attention to the Word Gap has been
favorable. Some scholars suggest that the Word
Gap is only the most recent vestige of a tendency
to consider non-mainstream ways of speaking as
