Fertility in colloquial terms refers the ability to have offspring. In demographic contexts, fertility refers to the actual production of offspring, rather than the physical capability to reproduce, which is termed fecundity. The fertility rate is the average number of children born during an individual's lifetime. In medicine, fertility refers to the ability to have children, and infertility refers to difficulty in reproducing naturally. In general, infertility or subfertility in humans is defined as not being able to conceive a child after one year (or longer) of unprotected sex. The antithe

The Great Replacement, also known as replacement theory or great replacement theory, is a debunked white nationalist far-right conspiracy theory coined by French author Renaud Camus. Camus's theory states that, with the complicity or cooperation of "replacist" elites, the ethnic French and white European populations are deliberately being replaced by non-white peoples—especially from Muslim-majority countries—through mass migration, demographic growth and a drop in the birth rate of white Europeans. Since then, similar claims have been advanced in other national contexts, notably in the United States. A consensus of academic scholars have dismissed these claims of a conspiracy of "replacist" elites as rooted in a misunderstanding of demographic statistics and premised upon an unscientific, racist worldview.

Fecundity is a descriptor of productivity that can be defined in multiple ways; including the capability to produce offspring. It may refer to the level of fertility of human, animal, and organic life as measured by the number of gametes (eggs), seed set, or asexual propagules. Additionally, it is the potential for reproduction of a recorded population as opposed to a sole organism.

sociological concept

Remarriage is a marriage that takes place after a previous marital union has ended, as through divorce or widowhood. Some individuals are more likely to remarry than others; the likelihood can differ based on previous relationship status (e.g. divorced vs. widowed), level of interest in establishing a new romantic relationship, gender, culture, and age among other factors. Those who choose not to remarry may prefer alternative arrangements like cohabitation or living apart together. Remarriage also provides mental and physical health benefits. However, although remarried individuals tend to ha

Twixter is a neologism that describes a new generation of young adults in the United States and other industrialized countries who are trapped, in a sense, betwixt (between) adolescence and adulthood. This Western neologism is somewhat analogous to the Japanese term parasite single. The Twixter phenomenon was discussed in the 2005 issue of Time.

Self-segregation or auto-segregation is the separation of a religious, ethnic, or racial group from other groups in a country by the group itself naturally. This usually results in decreased social interactions between different ethnic, racial or religious groups and can be classed as a form of social exclusion.
