Which statement best defines demography?
• the study of age increases over time in a certain area
• the study of the location of human populations
• the study of changes that occur over time in human populations
• the study of population growth over time
• the study of changes that occur over time in human populations
what is meant by “natural population growth”
increase due to a rise in birthrates
increase due to change in populations in other states
increase due to immigration from other countries
increase due to migration from other states
"Natural population growth" refers to the increase in population that occurs as a result of the difference between the number of births and the number of deaths in a given area or population over a certain period of time. It does not include any migration or immigration from other places. Therefore, it refers to an increase due to a rise in birthrates minus deaths.
by how much is the Hispanic population Texas public schools expected to increase by 2040
24 percent
93 percent
141 percent
213 percent
According to a report by the Texas State Data Center, the Hispanic population in Texas public schools is expected to increase by 93 percent by 2040.
about what percent of the population increase in Texas is due to people moving in the states
12 percent
22 percent
32 percent
42 percent
According to the US Census Bureau, from 2010 to 2019, about 54% of Texas' population growth was due to people moving in from other states. So, the percentage of population increase in Texas due to people moving in the state is approximately 54%. This is higher than all of the options given in the question.
why have 79 counties in Texas seen a decline in population even though the state population as a whole grew
death rates are higher in other counties
Urban growth made up for lost population in rural counties
people migrated to the states of those counties
people migrated from coastal counties to inland counties
The reason that 79 counties in Texas have seen a decline in population despite the overall growth of the state's population is due to urbanization and economic opportunities concentrated in the urban counties. As a result, people from rural counties often migrate to more urban areas with better economic prospects, leading to a decline in population in those rural counties. So, the correct option is: "Urban growth made up for lost population in rural counties."
The best statement that defines demography is: "the study of changes that occur over time in human populations."
To arrive at this answer, let's break down each option:
1. "The study of age increases over time in a certain area" is not a comprehensive definition of demography. While age is an important aspect of demography, it is just one of the many factors studied in the field.
2. "The study of the location of human populations" is more closely related to the field of geography rather than demography. While demographers do analyze population distribution, it is not the sole focus of their studies.
3. "The study of changes that occur over time in human populations" is a broader and more accurate definition of demography. Demographers examine various changes in human populations, such as birth rates, death rates, migration patterns, and population growth or decline.
4. "The study of population growth over time" is too narrow as it does not encompass all the aspects that demography covers. Population growth is certainly a key component of demography, but the field also encompasses other population dynamics and changes.
Therefore, option 3, "the study of changes that occur over time in human populations," is the most comprehensive and accurate definition of demography.
