Reassessing the Standard of Living
in the Soviet Union:
An Analysis Using Archival and
Anthropometric Data

“The greatest failed experiment in the history
of the human race.”
-- Joel Mokyr
on the Soviet Union
Did the standard of living improve in the Soviet
Union in the postwar period?
• GNP grew in every decade
• But know little about standard of living: little data; some
unfavorable trends
• Important: our judgment of the Soviet growth model depends in
part on whether growth translated into improved well-being for
the population as a whole
This paper:
• Examines alternative measures of well-being: birth weights;
child and adult heights; infant and adult mortality
• Useful supplement to traditional measures of living
standards, especially where economic data is of poor quality
and reliability
• Previously unexploited data sources

US; ‘early industrial growth puzzle’ in Europe

“The fundamental problem in evaluating Soviet growth
is data quality.”
-- Easterly and Fischer, 1994
Problems with Soviet economic statistics
• Strong incentives for overreporting output
• Methodological differences between Soviet and western national
income accounting practices
• Selective publication of data
• Shortages; poor quality of goods; lack of market prices
• Growing underground economy

New data sources
• Data on infant and adult mortality from the Soviet archives:
by region, urban/rural, age and sex (adult mortality) for 1959,
1970 and 1979
• Additional (limited) archival and published data on wages, health
care infrastructure, food and alcohol consumption
• Anthropometric data: birth weights and child heights across
regions, 1910s - present; adult heights from the Russian
Longitudinal Monitoring Survey
Advantages of anthropometric and
mortality data:
• More objective measures of well-being than economic growth or
consumption
• Not affected by data problems inherent in more conventional
measures
• Take into account that some economic activity is non-monetized
Insights from anthropometric data
• Adult height is a cumulative measure of nutritional status in
infancy and childhood; measures net nutrition
• Fogel and others: height can provide a wealth of information on
living standards; height and income highly correlated
• At the population level nearly all differences in average height
are due to environmental influences: can compare stature
across countries and over time
Soviet Anthropometric Data
(1) Child height data:
• Most collected by the Semashko Inst. of Public Health from
1920s to present
• 59 Russian regions and most USSR republics
• Collected in preschools and schools; at least 100 children of
each sex age each age (n = 165 on average)
• Underlying RSFSR data represent average heights of over
470,000 children
• Average child heights converted into percentiles of US growth
standards, from (old) standard US growth charts
Soviet Anthropometric Data, cont.
Possible problems with child height data:
• Researchers sometimes excluded children with “defects” and
chronic illnesses
• Urban areas sampled more frequently; urban stature is greater
on average than rural stature
• Surveys not representative of USSR or RSFSR
• If better-off children more likely to go to school, will overestimate heights (schooling became compulsory in 1958)

What caused the improvement and subsequent
stagnation in population health status?
1.
Possible explanations for improvement:
•
Development and expansion of national health care system;
particularly effective at controlling infectious diseases
•
Significant increases in female education
•
Improvement in caloric and nutrient content of the food supply
•
Urbanization (clean water, sewers, heat, etc.)
Possible causes, cont.
2.
Possible explanations for stagnation/decline:
•
Changes in diet; poor agricultural harvests
•
Increase in alcohol consumption
•
Increase in military expenditures crowding out domestic
consumption
•
Increased macroeconomic imbalances leading to decreased
availability of consumer goods

Conclusion: Did the standard of living rise or fall in the
Soviet Union in the postwar period?
• Given poor quality of GNP data, trends portrayed by stature
and death rates may be more believable than GNP growth
• Conventional measures of GNP growth and consumption
indicate a long, upward climb in living standards 1950-1989
• Corroborated for 1950 – 1970 by increasing child and adult
heights, declining IMR and rising life expectancy at birth
Conclusion, cont.
•
But evidence of deteriorating living conditions in the mid- to late-1960s:
– declining male life expectancy
– rising infant mortality, even in regions with reliable vital event data
– stagnation or decrease in child heights;
– slight decline or stagnation in height of men and women born in
early 1970s
•
Underlying reasons for these trends are inconclusive, but may include:
– expansion of national health system
– increased education
– declining availability of consumer goods
– increased alcohol consumption
Implications and further research
• More data on food and alcohol consumption, tobacco use
• Effect of abortion legalization on child and parent/adult
outcomes
• Effect of Chernobyl on child well-being
• Are deteriorating living conditions of the 1970s related to current
high mortality levels in Russia?
