  1. 1. Environmental factors that affect population size regardless of the population density, such as natural disasters.
  2. 6. The process by which an increasing percentage of a population comes to live in urban areas, typically associated with industrialization.
  3. 8. The measure of the number of deaths in a given population, expressed as a percentage or per 1,000 individuals.
  4. 10. A condition where the number of people exceeds the capacity of the environment to support life at a decent standard of living.
  5. 11. The number of individuals living per unit of area, often expressed as people per square kilometer or square mile.
  6. 13. A graph that represents the number of individuals from a cohort that will survive to different ages, illustrating patterns of morality.
  7. 16. The number of deaths per 1,000 people in a given year within a population.
  8. 18. The movement of people from one place to another, which can affect population size and composition.
  9. 19. Environmental factors whose effects on the population change as the population density changes, such as competition for resources.
  10. 23. The period it takes for a population to double in size, often expressed in years.
  11. 24. The average period that a person can expect to live, often influenced by factors such as healthcare, lifestyle, and living conditions.
  12. 26. A mathematical formula used to estimate the number of years required for a population to double by dividing 70 by the annual growth rate.
  13. 27. A situation where a population exceeds the carrying capacity of its environment, leading to resource depletion.
  14. 28. Species that produce many offspring with little investment in their care, often found in unstable or unpredictable environments.
  15. 29. The ability to maintain certain processes or states indefinitely, often in relation to environment and resource management.
  16. 30. A resource that is in short supply and restricts the growth, distribution, or abundance of a population.
Down
  1. 2. The difference between the number of immigrants and migrants in a population over a specific period, expressed per 1,000 individuals.
  2. 3. The potential reproductive capacity of an individual or population, often measured by the number of offspring produced.
  3. 4. The number of live births per 1,000 people in a given year within a population.
  4. 5. Species that produce fewer offspring but invest more resources in their upbringing, leading to higher survival rates in stable environments.
  5. 7. The model that describes the transition from high birth and death rates to lower birth and death rates as a country develops.
  6. 9. The average number of children that a couple must have to replace themselves in the population, typically estimated at about 2.1 children per women in developed countries
  7. 12. Nations with advanced economies, high standard of living, and significant industrialization, typically characterized by higher levels of income and education.
  8. 14. The movement of individuals into a population from other areas, contributing to population growth.
  9. 15. The average number of children born to a woman over her lifetime.
  10. 17. Nations with low levels of industrialization, low income per capita, and generally lower standards of living.
  11. 20. The death of infants before their first birthday, often used as an indicator of the overall health and well-being of a population.
  12. 21. The maximum number of individuals of a species that an environment can sustainably support without degrading the ecosystem.
  13. 22. The average number of children a woman would have during her lifetime based on current-age fertility rates.
  14. 25. The movement of individuals out of a population to other areas, leading to a decrease in population size.
