While men have always received more education than women in the past, this gender imbalance has turned around large parts of world. In many countries, now excel terms participation and success higher education. This implies that, for first time history, there are highly educated reaching reproductive ages looking a partner. We develop an agent-based computational model that explicates mechanisms may linked reversal inequality with observed changes educational assortative mating. Our builds...
Abstract Background In the absence of medical treatment and vaccination, individual behaviours are key to curbing spread COVID-19. Here we describe efforts collect attitudinal behavioural data disseminate insights increase situational awareness inform interventions. Methods We developed a rapid collection monitoring system based on cross-national online survey, “COVID-19 Health Behavior Survey”. Respondent recruitment occurred via targeted Facebook advertisements in Belgium, France, Germany,...
The emergence of disliking relations depends on how adolescents perceive the relative informal status their peers. This phenomenon is examined a longitudinal sample using dynamic network analysis (585 students across 16 classes in five schools). As hypothesized, individuals dislike those who they look down (disdain), and conform to others by as being looked peers (conformity). inconsistency between perceptions also leads disliking, when do not up be admired (frustration). Adolescents are...
Abstract Physical distancing measures are intended to mitigate the spread of COVID-19, even though their impact on social contacts and disease transmission remains unclear. Obtaining timely data contact patterns can help assess such protective measures. We conducted an online opt-in survey based targeted Facebook advertising campaigns across seven European countries (Belgium, France, Germany, Italy, Netherlands, Spain, United Kingdom (UK)) States (US), achieving a sample 53,708...
Abstract In the absence of medical treatment and vaccination, individual behaviours are key to controlling spread COVID-19. We developed a rapid response monitoring system through an online survey (the “COVID-19 Health Behavior Survey”). Participant recruitment takes places continuously via Facebook in eight countries (Belgium, France, Germany, Italy, Netherlands, Spain, United Kingdom, States). The collects information on people’s health, attitudes, behaviours, social contacts. this paper,...
Objectives We investigate changes in social contact patterns following the gradual introduction of non-pharmaceutical interventions and their implications for infection transmission early phase pandemic. Design, setting participants conducted an online survey based on targeted Facebook advertising campaigns across eight countries (Belgium, France, Germany, Italy, Netherlands, Spain, UK USA), achieving a sample 51 233 questionnaires period 13 March–12 April 2020. Poststratification weights...
The spread of digital technologies and the increased access to internet has contributed production accumulation unprecedented quantities data about human behavior. Demographers, who have a long-standing interest in issues related quality, are an ideal position make sense this new information. This paper discusses three ways which Data Revolution created novel sources for demographic research. It unique technical ethical challenges posed by these opportunities they provide understanding...
Recent evidence from the United States suggests that reversal of gender gap in education was associated with changes relative divorce risks: hypogamous marriages, where wife more educated than husband, used to have a higher risk hypergamous husband educated, but this difference has disappeared. One interpretation holds may result cultural change, involving increasing social acceptance hypogamy. We propose an alternative mechanism need not presuppose change: gender-gap changed availability...
Surveys of the general population can provide crucial information for designing effective nonpharmaceutical interventions to tackle public health emergencies, such as COVID-19 pandemic. Yet, conducting surveys be difficult, especially when timely data collection is required. In this viewpoint paper, we discuss our experiences with using targeted Facebook advertising campaigns address these difficulties in relation We describe central advantages, challenges, and practical considerations. This...
Status beliefs link social distinctions, such as gender and race, to assumptions about competence worth.Recent modeling work in status construction theory suggests that interactions small, task focused groups can lead the spontaneous emergence diffusion of larger populations.This earlier has on dyads smallest possible which might emerge from face-to-face interaction.In today's societies, however, many take place than dyads.In this article, we therefore develop an agent-based computational...
Abstract Background Physical distancing measures aim to reduce person-to-person contact, a key driver of transmission respiratory infections such as SARS-CoV-2. In response unprecedented restrictions on human contact during the COVID-19 pandemic, number studies measured social patterns under implementation physical measures. This rapid review aims synthesize empirical data changing pandemic. Method We conducted systematic using PubMed, Medline, Embase and Google Scholar following Preferred...
Digital and computational demography explores in relation to the digital revolution – rapid technological improvements digitized information storage, power spread of internet mobile technologies since turn new millennium. We cover three ways which touches upon demography. First, we discuss how technologies, through their impacts on daily lives shifting individuals access information, communicate services, have implications for demographic outcomes linked health mortality, fertility family,...
Lau and Murnighan’s faultline theory suggests that strong demographic faultlines can undermine cohesion in work teams. A splits a team into internally homogeneous but mutually dissimilar subgroups based on characteristics. Social influence processes within these then lead to the polarization of members’ attitudes along divisions imposed by faultline. However, hitherto neglects effects attitude certainty. Research shows certainty with which individuals hold their affects social processes. We...
Abstract In response to the increasingly complex and heterogeneous immigrant communities settling in Europe, European countries have adopted various civic integration measures. Measures aiming facilitate language acquisition are considered crucial for cooperation between immigrants natives. Simultaneously, rapid expansion of social media usage is believed change factors affecting immigrants’ acquisition. However, only a few previous studies analyzed whether this case. This article uses novel...
We study how the status characteristics gender and ethnicity affect abilities that adolescents attribute to each other in Hungarian school context. For this, we derive predictions from theory test by applying exponential random graph models data collected among students 27 classes. By that, contribute few existing studies of a context, propose novel approach handle structural dependencies between individual ability attributions. Our results suggest across classes, does not consistently...
Abstract Social scientists increasingly use Facebook’s advertising platform for research, either in the form of conducting digital censuses general population, or recruiting participants survey research. Both approaches depend on accuracy data that Facebook provides about its users, but little is known how accurate these are. We address this gap a large-scale, cross-national online (N = 137,224), which we compare self-reported and Facebook-classified demographic information (sex, age region...
Abstract Online labor markets—freelance marketplaces, where digital is distributed via a web-based platform—commonly use reputation systems to overcome uncertainties in the hiring process, that can arise from lack of objective information about employees’ abilities. Research shows, however, tend create winner-takes-all dynamics, which differences candidates’ reputations become disconnected their In this paper, we an empirically validated agent-based computational model investigate extent...
Social scientists increasingly use Facebook's advertising platform for research, either in the form of conducting digital censuses general population, or recruiting participants survey research.Both approaches depend on reliability data that Facebook provides about its users, but little is known how reliable these are.We address this gap a large-scale, cross-national online (N = 137,224), which we compare self-reported and Facebook-classified demographic information (sex, age, region...
Abstract In Western countries, the distribution of relative incomes within marriages tends to be skewed in a remarkable way. Husbands usually do not only earn more than their female partners, but there is also striking discontinuity contributions household income at 50/50 point: many wives contribute just bit less or as much husbands, few more. This ‘cliff’ has been interpreted evidence that men and women avoid situations where wife would her husband, since this go against traditional gender...
