Conclusion Higher satisfaction with housing and income was associated with better self-rated health. Therefore, studies on the social determinants of health should not only focus on objective material conditions but also on how individuals perceive and evaluate their situation. Keywords: life course epidemiology, health inequalities, epidemiology, public health, social medicine Strengths and limitations of this study Our analysis is based on data from the German Socio-Economic Panel study GSOEP , a panel survey that is representative of the population in Germany.
In contrast to previous studies, our results are based on fixed effects models that account for all stable hard-to-observe confounders e. However, reverse causation i. Thus, our results are likely unbiased by confounding but potentially biased by reverse causation i. Introduction With regard to health, it is relevant not only what the objective situation of an individual looks like but also how that situation compares to others. In contrast, the concept of relative deprivation implies that individuals compare themselves to others in certain groups.
Reference groups might be a a group that the individual wants to become a part of normative reference group , b the group that they are already a member of membership group or c a group that the individual estimates as most contrastive comparative reference group.
It can be assumed that it is not important to whom individuals are comparing themselves but that it is relevant whether they achieve positive or negative results. These feelings can affect health via risky health behaviours e. In his study, Miething found that the effect of income satisfaction on mortality remained after controlling for income position, educational attainment and employment status, concluding that income itself does not cover the whole spectrum of perceived inequalities.
Furthermore, little is known about whether the association between satisfaction and health varies over different life stages. Studies have shown that income is a strong predictor for health and well-being at different ages. Potential age differences are implied in the model of sensitive periods, 27—30 where it is stated that socially relevant periods, such as entry into the job market, parenthood or the transition into retirement, may have an impact on the development of health.

The analysis here is based the Federal Reserve's triennial SCF, which provides a nearly comprehensive snapshot of the balance sheets and incomes of U. Return to text 4. One type of risk associated with traditional DB plans is often ignored in this calculus. If a worker separates from the employer or loses their job mid-career, they forego most of the value of promised benefits, because DB formulas are generally based on years of service and some measure of "highest" earnings.
Employers can and many have shut down DB plans, leaving workers with much less than they would have expected in terms of retirement wealth. In contrast, the assets in DC plans are perfectly portable, and are, from that perspective, actually less risky than DB for early and mid-career workers.
Return to text 5. In this figure and elsewhere , families are sorted into wealth quartiles within their ten-year birth cohort. If we sorted everyone by wealth in one large group regardless of age, the wealthiest group would be dominated by the oldest families who have accumulated more wealth because of where they are in the lifecycle. By sorting within age groups, we remove those lifecycle effects, and thus for example the top quartile is equally represented by the top quartile within each birth cohort.
Return to text 6. In some sense, though, federal workers have been unique since the s, because their plan have not further evolved into a DC only as most private sector plans. Return to text 7. See, for example, figure 8. Return to text 8. Return to text 9. Return to text Some of those liabilities show up in the FA insurance sector, as employers make the necessary payments to establish DB annuities.
The FA bookkeeping acknowledges that the actual assets such as stocks and bonds plan sponsors hold may not be sufficient to meet all of the plan obligations, because that will ultimately depend on the uncertain returns on those stocks and bonds.
Thus, there is an underfunding adjustment that equalizes the household sector assets and plan sponsor liabilities. The issue of DB pension funding status is an interesting but controversial topic, involving assumptions about inflation, real rates of return to various assets, and appropriate risk-adjusted discounting.
We choose to avoid those debates in this Note. In any event, the impact on our wealth distribution estimates is limited to how we distribute the relatively small underfunded portion. Dettling, et al. The Stata code that generates DB wealth estimates for the SCF survey years through is available from the authors upon request. Questions about survivor benefits and inflation adjustment are also asked of current recipients in the SCF, and those answers are also used to choose the appropriate mortality and discount rate inputs for the present value calculations.
For nominal interest rates, we use estimates from the Bureau of Economic Analysis BEA with a benchmark to a 3 percent real rate. The distinction between termination and continuation values is a corollary to the discussion of DB risk in footnote 4, above.
The assertion that early to mid-career workers face risk under the DB because they may lose or leave the job, or because the employer may terminate or change the plan, is equivalent to saying the plan has a low termination relative to the continuation value for those workers. We are grateful to Chichun Fang for running the termination simulation on the HRS data that made it possible for us to solve for the wedge between private and public plan generosity and validate the statistical relationship between age, earnings, years in plan, sector, and plan termination value.
Our approach to estimating termination values for current job DB plans effectively ignores variation in expected DB benefits that is not explained by age, years of plan coverage, earnings, and sector. The HRS simulations provided by Chichun Fang show that about seventy percent of the variation in termination values is explained by just those four variables. Thus, the only potential bias in our approach is if the remaining thirty percent of variation in termination values is correlated with some other variable we are using in the tabulations, that is, the other components of household wealth.
Henriques et al. These numbers are for the s birth cohort. The Congressional Budget Office reports projected replacement rates by birth cohort, lifetime income, and various policy scenarios in their annual report on Social Security. The balance in the fund is mostly an accounting exercise, because the bonds held are both liabilities and assets of the same government. However, it is an important accounting exercise, because it provides information about much a given birth cohort has paid in taxes relative to the benefits they will receive.
The present value of benefits is calculated for all workers in the system ages 15 and older. The age group 50 to 59 is chosen because most are still working, so we directly observe the relevant earnings measures, but they are close enough to retirement that we have a good sense of their retirement resources. The table excludes the relatively few families in this age group where neither the head or spouse is still working. The income measure is the SCF "usual" income measure that is close to the preferred economic "permanent income" concept.
The SCF is unique among household surveys in terms of "oversampling" very wealthy families, and thus the value for average income in the top wealth quartile is itself dominated by the very wealthiest families, those in the top 1 percent.
This is not the same as the actual quantile values themselves, which are the boundary between categories. To explore estimating Gini coefficients from this type of binned data I used data from the wonderful Lakner-Milanovic World Panel Income Distribution database , which is available for free download. This useful collection contains the mean income by decile bin of many countries from onwards - the result of some careful and doubtless very tedious work with household surveys from around the world.
But my hunch was that this would underestimate inequality, because of the straight lines in the Lorenz curve above which are a simplification of the real, more curved, reality. To investigate this issue, I started by creating a known population of 10, income observations from a Burr distribution , which is a flexible, continuous non-negative distribution often used to model income. Doing this for 10 bins is the equivalent of calculating a Gini coefficient directly from decile data such as in the Lakner-Milanovic dataset.
Around 25 bins needed for a really good estimate. Maybe I should have stopped there; after all, there is hardly any difference between 0. But I wanted to explore if there were a better way. They are generally used for large data sets and are often invoked by politicians and economists to discuss economic and social justice concepts.
Depending on the size of the population, alternatives to quintiles include quartiles and tertiles. Understanding Quintiles A quintile is a type of quantile, which is defined as equal-sized segments of a population. One of the most common metrics in statistical analysis, the median, is actually just the result of dividing a population into two quantiles. A population split into three equal parts is divided into tertiles, while one split into fourths is divided into quartiles.
The larger the data set, the easier it is to divide into greater quantiles. Economists often use quintiles to analyze very large data sets, such as the population of the United States. There would be three quintiles in between the upper and lower quintiles. While the average of all the stock prices typically falls between the second and fourth quintiles, which is the middle point of the data, outliers on either the high end or the low end of the data may increase or decrease the average value.
As a result, it is worth considering the distribution of the data points—and accounting for any significant outliers—when trying to understand the data and the average values.
