1968年，密歇根大学的调查研究中心开始收集各类关于个人，家庭的数据。其中包罗万象，从收入，职业，教育背景，贷款，医疗保险甚至到孩子的时间分配，零用钱等等都有所关注。

1968年时，参与调查的有4800个家庭，而到2001年时，这个数目已经增加到7000个。PSID追踪了65000个个人在36年间的生活和各类经济活动。

一些比较有意思的关于PSID的研究课题包括了

Game-theoretic interactions among family members (market work and housework of spouses, control of finances measured as of 1999, separate pensions and intrafamily bargaining);

Theories of the impact of technical change on earnings and life-course mobility across occupations and industries;

Models of spatial equilibrium and neighborhood effects tested by spatial analysis models using geocode data as input;

Models of bequests and altruism tested with savings, wealth and gifts measures;

Models of intergenerational mechanisms in social and economic life tested with multigenerational data;

Life-course stress and mortality theories tested with long-term health and mortality measures;

Theories of social acceptance or ‘stigma’ tested with models used to understand the rise in bankruptcy beyond that predicted by financial gains from declaring bankruptcy under Title 7 or 13;

Changes in welfare and incentives for saving by low income families;

Long-term effects of economic conditions of the family during early childhood;

Family adaptation to change, including immigration to the United States;

How labor markets adjust and workers make commitments to large durables (autos) during different stages of the business cycle;

How strong the spending stimulus is from the ‘wealth effect’ of stock market gains;

Whether the wealth effect, including wealth from pension balances in equities, can explain much of the low U.S. savings rate;

Participation of younger and less educated employees in company-sponsored pension plans;

Long-term effects of health capital as indexed by healthful activities, nutrition and maintaining proper weight on economic well-being;

Models of product space competition—how consumers select among the bewildering array of vehicle types;

How income and wealth mobility compare in the United States, Sweden and Germany;

What share of total wealth is in the form of pensions and whether it protects the ‘grasshoppers’ (those with hyperbolic discounting) who would otherwise save little for retirement; 

Whether Baby Boomers really are bigger spendthrifts than earlier cohorts and if so, whether this is because they expect transfers from their parents;

Cross-national comparative research on demographic trends and behavior;

Multidisciplinary and life-course research on the roles that the family, school and neighborhood play in fostering or hindering children's learning at home and at school;

Social and economic determinants and consequences of caring for elderly parents;

Time use studies as indicators of social and economic well-being of children;

The effect of early human capital investment on children’s development;

Patterns, causes and consequences of union formation behavior; and

Family processes as mediators of how socio-economic characteristics, neighborhood and policies affect children’s cognitive, emotional, and physical well-being.
