Currently, a social security number (SSN) is held by almost every legal resident of the United States and works as an important numbering system. However, this was not the case in the early years of the Social Security program and historical changes in SSN holder rates had not been examined sufficiently. It is important to understand the changes in health policies and situations. Thus, the present article examined historical changes in the rates of SSN holders in the United States between 1909 and 2019. Analyses demonstrated that the rates clearly increased. Specifically, in Phase 1 (1909-1919), the rates were low in the early period, but they increased markedly. In Phase 2 (1919-1952), the rates continued to increase gradually. In Phase 3 (1952-2019), the rates were almost 100% and reached saturation. This basic information leads to a better understanding of the health policies and situations, contributing to medical and social science research.

AbstractAt least two twin registries in the United States have been or are being assembled using the similarity of Social Security Numbers in computerized records to help identify possible twin pairs. While the success of such enterprises depends directly on a high probability of twinness given Social Security Numbers, there are theoretical and practical reasons to study the probability of Social Security Number similarity given twinness. For example, the number of twin pairs with similar Social Security Numbers obviously determines the maximum number of twin pairs that can be discovered by similarity algorithms. To study this issue, we examined the similarity of known Social Security Numbers in twin pairs from the Virginia Twin Registry by age, sex, race, and zygosity of the pair. We found that similarity between the Social Security Numbers of twin pairs varies markedly by age, and MZ twin pairs have significantly more similar Social Security Numbers than DZ pairs at all ages. Among older twins, there are also significant differences by sex and race. For younger twins, algorithms that identify putative twin pairs on the basis of the similarity of their Social Security Numbers hold the promise of being able to identify a large proportion of all true twin pairs. Such algorithms will be substantially less successful, however, in identifying a large proportion of older twin pairs.

Abstract Populist radical right (PRR) parties have been steadily expanding, not only in the number of supporters they gain and the seats they win in governments, but more importantly they have been increasingly elected into governmental coalitions as well as presidential offices. With the prominence of these authoritarian, nationalistic and populist parties, it is often difficult to discern what kind of policies they actually stand for. Particularly with regards to the welfare state and public health, it is not always clear what these parties stand for. At times they call for a reduction of health-related welfare provision, despite the fact that this goes against the will of the “ordinary people”, their core supporters; they often promote radical reductions of welfare benefits among socially excluded groups - usually immigrants, whom are most in need of such services; and finally they often mobilize against evidence-based policies. The purpose of this workshop is to present the PRRs actual involvement in health care and health policies across various countries. As PRR parties increase and develop within but also outside of the European continent it is necessary to keep track of their impact, particularly with regards to health and social policies. Although research surrounding PRR parties has significantly expanded over the last years, their impact on the welfare state and more specifically health policies still remains sparse. This workshop will present findings from the first comprehensive book connecting populist radical right parties with actual health and social policy effects in Europe (Eastern and Western) as well as in the United States. This workshop presents five country cases (Austria, Poland, the Netherlands, the United States) from the book Populist Radical Right and Health: National Policies and Global Trends. All five presentations will address PRR parties or leaders and their influence on health, asking the questions “How influential are PRR parties or leaders when it comes to health policy?” “Do the PRR actually have an impact on policy outcomes?” and “What is the actual impact of the health policies implemented by PRR parties or leaders?” After these five presentations, the participants of the workshop will be engaged in an interactive discussion. Key messages As the number of PRR parties increase worldwide and their involvement in national governments become inevitable, new light must be shed on the impact these political parties have on public health. Politics needs to become better integrated into public health research. The rise of PRR parties in Europe might have serious consequences for public health and needs to be further explored.
