How does the association between gender attitudes and housework share vary across countries and time? We examine the second demographic transition as it unmasks in the association between gender attitudes and housework participation. Using data of the 2002 and 2012 International Social Survey Programme (ISSP) for 24 countries, we find that the association between gender attitudes and housework share became stronger over time in most countries, signifying that the second demographic transition was in place. The results also show that the association varied across the 24 countries, reaching an equilibrium in many but at different stages. Our findings suggest that equilibria in the domestic division of labour take various forms and paces in the ISSP countries.
TRAPPIST-1 Family of Planets: Rocky Through and Through?
Precise measurements reveal that the exoplanets have remarkably similar densities, which provides clues to their composition
Measuring the mass and diameter of a planet reveals its density, which can give scientists clues about its composition. Scientists now know the density of the seven TRAPPIST-1 planets with a higher precision than any other planets in the universe, other than those in our own solar system. Credit: NASA/JPL-Caltech.
The more precisely scientists can measure a planet’s density, the more they know about what it’s made of. The TRAPPIST-1 planetary system home to the largest batch of roughly Earth-sized planets ever found has offered astronomers a glimpse at the possible diversity among rocky worlds in the universe, including the Earth.
