The Basic Social Indicators Questions
• How are we doing?
• More specifically, with respect to
children, how are the kids
(including adolescents and youths)
doing?

CWI
The Basic Social Indicators Questions
These questions can be addressed by comparisons:
 to past historical values,
 to other contemporaneous units (e.g., comparisons
among subpopulations, states, regions, countries),
or
 to goals or other externally established standards,
The Child and Youth Well-Being Index (CWI),
described below, uses all three points of
comparison.

What is the CWI?
• A composite measure of trends over time in
the quality of life, or well-being, of
America’s children and young people.
• It consists of several interrelated summary
or composite indices of annual time series
of 28 social indicators of well-being.

The Principal Objective
of the CWI:
• To give a sense of the overall direction of
change in the well-being of children and
youth in the United States as compared to
1975.

The CWI is designed to address the
following types of questions:
• Overall, on average, how did child and youth
well-being in the United States change in the
last quarter of the 20th century and into the
present?
• Did it improve or deteriorate, and by how
much?
• In which domains or areas of social life?

Methods of Index Construction
• Annual time series data (from vital statistics and sample
surveys) have been assembled on some 28 national level
indicators in seven quality-of-life domains.

Family Economic Well-Being

• These seven domains have been wellestablished in over two decades of empirical
studies of subjective well-being, including
studies of children and youths, by social
psychologists and other social scientists.
• In this sense, the CWI is an evidence-based
measure of trends in averages of the social
conditions encountered by children and youths
in the United States.

• Each of the 28 Key Indicators is indexed by
percentage change from the base year, 1975.
– That is, subsequent annual observations are
computed as percentages of the base year.
– Three indicators begin in the mid-1980s and use
corresponding base years.
• The base year is assigned a value of 100.
– The directions of the indicator values are oriented
such that a value greater (lesser) than 100 in
subsequent years means the social condition
measured has improved (deteriorated).
13
FCD CWI

CWI
• The time series of the 28 indicators are grouped
together into the seven domains described
above and domain-specific summary well-being
indices are constructed.
– Within these summary indices, each indicator is
equally weighted.
• The seven component indices are then
combined into the equally-weighted composite
Child and Youth Well-being Index (CWI).

On Equal Weighting
 In an article on statistical methodology, Hagerty and Land
(2007) consider the general question of how to construct
composite, summary indices for a social unit that will be
endorsed by a majority of its members.
 They assume that many social indicators are available to
describe the social unit, but individuals disagree about the
relative weights to be assigned to each social indicator.
 The composite index that maximizes agree among
individuals can then be derived, along with conditions
under which an index will be endorsed by a majority in the
social unit.
15
FCD CWI
FCD
CWI
On Equal Weighting
 Using both a theoretical analysis of a statistical model to
measure the extent of agreement among individuals and
computer simulations, Hagerty and Land (2007) show that
intuition greatly underestimates the extent of agreement
among individuals, and that it is often possible to construct
a composite index with which most individuals agree (at
least in direction).
 In particular, they show that the equal-weighting strategy
is privileged in that it is what statisticians call a minimax
estimator—it minimizes disagreement among all possible
individuals’ weights for the indicators. Hagery and Land
(2007) demonstrate these propositions by calculating real
composite quality-of-life indices from two sample surveys
of individuals’ actual importance weights.
 Some illustrations from Hagerty and Land (2007) follow.

Figure 1 shows that improvements in the CWI
essentially have slowed and stalled in the early years
of this first decade of the 21st century.
Just as the CWI allowed us be the first to signal that
the steady increases in numerous Key Indicators in
the period 1994-2002 were indicative not just of
isolated trends, but rather of an overall improvement
in well-being, the CWI now is telling us that this
trend of overall improvement has come to an end.

Index Validation
Do changes in the CWI actually indicate
anything about trends in the subjective wellbeing of America’s children/youths?
To address this question, Land, Lamb,
Meadows, and Taylor (2007) compared
trends in the CWI with those of smoothed
data on overall life satisfaction for High
School Senior from the Monitoring the

Race/Ethnic Disparities and Trends
In brief, the CWI tells us something about
trends in child and youth well-being in the
U.S. across the past three decades and
appears to have some validity. But are the
trends concentrated only among the white
majority kids and not shared in general?

How well are America’s children and youth
doing in recent years as compared to the

International Comparisons of
Child and Youth Well-Being
• To address this question, we compare U.S.
trends in child and youth well-being with
those of four other English-speaking
counties, specifically:
–
–
–
–
Australia,
Canada,
New Zealand, and
the United Kingdom.
31
FCD CWI
FCD
CWI
These nations were chosen for a number
of reasons:
• all share a common language;
• Australia, Canada, New Zealand, and the U.S. are
former colonies of the United Kingdom;
• all five nations are liberal democracies that have
representative democratic forms of government;
• all five also place considerable emphasis on the use of
economic markets for the production and distribution
of goods and services; and
• because of all the above, all share some common
elements of culture.
32
FCD CWI
FCD
CWI
• We assembled data on 19 Key International
Indicators of child and youth well-being that
were measured around the year 2000.
• The 19 Key International Indicators can be
classified into 7 domains: Family Economic
Well-Being, Social Relationships, Health, Safety
and Behavior, Educational Attainment,
Community Connectedness, and Emotional
Well-Being.

• They range from ‘1’, the highest ranking

social relationships), which indicates the
lowest ranking among the five countries.

Trends and Implication of Our
International Comparisons:
Overall Conclusions:
Although no country outscores the United States on
all domains of child and youth well-being, our
comparison shows deficiencies in U.S. child and
youth well-being, particularly in Family Economic
Well-Being, Health, and Educational Attainment
domains.
On the other hand, the U.S. does relatively well on
indicators in the Safety/Behavior, Community
Connectedness, and Emotional Well-Being
domains.

Best-Practice Analyses
As noted earlier, the basic social indicators
question of how are we doing can be answered in
three ways.
In addition to comparisons with how we are doing
in comparison to the past and in comparison to
other countries or social units, we can address this
question in terms of comparisons to goals or other
externally-constructed standards.
40
FCD CWI
FCD
CWI
Best-Practice Analyses
An externally-constructed standard that we have
used for the CWI is a “best practice” standard,
where best practice refers either to the
 “best historical value” of each indicator ever
observed in the U.S., or to the
 “best internationally observed” value of each
indicator among countries for which data are
available.
41
FCD CWI
FCD
CWI
Best-Practice Analyses
Recent calculations of the values the CWI
would obtain if all of the 28 indicators were
at their best values are:
126.53 for historical best-practice U.S.
values, and
147.36 for international best-practice
values.

CWI
Conclusions
• Trends: The composite CWI indicates improvement in
overall child and youth well-being since the early-1990s to
levels just above those of a generation ago. Race/ethnic
disparities have decreased somewhat, but persist.
• International Comparisons: Among English-speaking
nations, child well-being in the U.S. appears to be in the
middle of the pack—ahead of New Zealand and the U.K.
but behind Canada and Australia.
• Best-Practice Analyses: These show that we could be
doing substantially better.
