Abstract
Using the 1996, 2001, and 2004 panels of the Survey of Income and Program Participation, this brief examines the likelihood that nonelderly individuals in families with children experience substantial drops in family income and recoveries from such drops. Over 13 percent of families see their incomes fall by half at some point over the course of a year with the lowest- and highest-income families the most likely to experience a substantial income loss. Further, only two in five individuals recover to at least 100 percent of their pre-drop income in the year after the drop.
Introduction
Policymakers and the public are increasingly sensing
that families are on their own, at the mercy of
uncontrollable events such as illness or downsizing
and at ever-increasing risk of suffering financial
losses and declines in their material well-being as a
result of these events. A spate of recent research has
begun to assess whether this perception is borne
out by data on income and earnings. Most of this
work has focused on the volatility of earnings and
income—for example, how much a family’s
income moves up or down from year to year1—
while some hones in on substantial declines in
income. The data and research generally support
the popular perception that income has grown
more volatile over time, although the magnitude
and timing of changes are sensitive to the data and
measure of income used, the period and population
studied, and the analytic approach taken.
A focus on volatility captures the uncertainty
families face in knowing what their income will
be from one year to the next; however, more
volatile incomes do not necessarily mean families
or individuals are worse off. Increased variance of
income over time also indicates that the income
distribution is becoming less rigid and that families
at the bottom are more likely to move up.
Indeed, increased mobility is the flip side of
increasing volatility.
In contrast, a focus on substantial income
losses captures the downside of volatility. Shortterm
losses are also important as even they can
disrupt family routines, elevate stress, and impede
the ability to plan in addition to reducing total
family resources. Each effect may have lasting
consequences for adults and children even if the
loss of income is short-lived.
This brief examines the likelihood that nonelderly
individuals in families with children experience
a substantial drop in family income as well
as the likelihood that their income returns to
pre-decline levels. We also put income drops in
context by examining how often these drops are
preceded by a short-term spike in income. We
use data from the 1996, 2001, and 2004 panels
of the Survey of Income and Program Participation
(SIPP). Unlike studies that rely on annual data,
we assess income changes (drops and recoveries)
over a shorter time horizon of four-month periods.
Steep income drops are common, with
13.6 percent of families seeing their incomes fall
by half at some point over the course of a year.
The likelihood of income drops across the
income distribution is U-shaped, with the lowestand
highest-income families the most likely to
experience a substantial income loss. Further,
only two in five individuals recover to at least
100 percent of their pre-drop income in the
year after the drop.
