Habitual residenceIn conflict of laws, habitual residence is the standard used to determine the law which should be applied to determine a given legal dispute or entitlement. It can be contrasted with the law on domicile, traditionally used in common law jurisdictions to do the same thing. Habitual residence is less demanding than domicile and the focus is more on past experience rather than future intention. There is normally only one habitual residence where the individual usually resides and routinely returns to after visiting other places.
Population growthPopulation growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020. The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100.
Choice of lawChoice of law is a procedural stage in the litigation of a case involving the conflict of laws when it is necessary to reconcile the differences between the laws of different legal jurisdictions, such as sovereign states, federated states (as in the US), or provinces. The outcome of this process is potentially to require the courts of one jurisdiction to apply the law of a different jurisdiction in lawsuits arising from, say, family law, tort, or contract. The law which is applied is sometimes referred to as the "proper law.
Population ageingPopulation ageing is an increasing median age in a population because of declining fertility rates and rising life expectancy. Most countries have rising life expectancy and an ageing population, trends that emerged first in developed countries but are now seen in virtually all developing countries. That is the case for every country in the world except the 18 countries designated as "demographic outliers" by the United Nations. The aged population is currently at its highest level in human history.
Population declinePopulation decline, also known as depopulation, is a reduction in a human population size. Over the long term, stretching from prehistory to the present, Earth's total human population has continued to grow; however, current projections suggest that this long-term trend of steady population growth may be coming to an end. Until the beginning of the Industrial Revolution, the global population grew very slowly, at about 0.04% per year. After about 1800, the growth rate accelerated to a peak of 2.
World populationIn demographics, the world population is the total number of humans currently living. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took over 200,000 years of human prehistory and history for the human population to reach one billion and only 219 years more to reach 8 billion. The human population has experienced continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was nearly 370,000,000.
Population ecologyPopulation ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment, such as birth and death rates, and by immigration and emigration. The discipline is important in conservation biology, especially in the development of population viability analysis which makes it possible to predict the long-term probability of a species persisting in a given patch of habitat.
Domicile (law)In law and conflict of laws, domicile is relevant to an individual's "personal law", which includes the law that governs a person's status and their property. It is independent of a person's nationality. Although a domicile may change from time to time, a person has only one domicile, or residence, at any point in their life, no matter what their circumstances. Domicile is distinct from habitual residence, where there is less focus on future intent.
Lex lociIn conflict of laws, the term lex loci (Law Latin for "the law of the place") is a shorthand version of the choice of law rules that determine the lex causae (the laws chosen to decide a case). When a case comes before a court, if the main features of the case (particularly the parties and the causes of action) are local, the court will then apply the lex fori, the prevailing municipal law, to decide the case. However, if there are "foreign" elements to the case, the court may then be obliged, under conflict of laws, to consider whether it has jurisdiction to hear the case (see forum shopping).
Conflict of tort lawsIn conflict of laws, the choice of law rules for tort are intended to select the lex causae by which to determine the nature and scope of the judicial remedy to claim damages for loss or damage suffered. The first attempts to establish a coherent choice of law rule for tort cases involving a foreign law element varied between favouring the lex fori (i.e. the law of the court) and the lex loci delicti commissi (i.e. the law of the place where the tort was committed).
