In A Nutshell

Demographic studies are important for urban planning to design sustainable communities. They allow planners to account for population growth and demand for housing, businesses, industries and institutions. Key factors like population projection, population growth, environmental quality and resource scarcity must be evaluated to achieve sustainable development. Demographic transition models show how birth and death rates change over time, shaping a population's age structure. Life expectancy estimates the average age of death in a group. Exponential and logistic growth curves model how populations change over different time periods based on carrying capacity and resources. Population pyramids illustrate age structures with many young people in rapidly growing populations with high birth and death rates.

In A Nutshell

Activity No. 2. Demographic studies play an important role in studying


human ecology and settlement patterns. It enables urban and
environmental planners to design sustainable communities with the utmost
comfort and responsiveness to the growing population growth and demand
for resources. Identifying the key factors affecting demography will shape
the idea of projecting future demand for residential units, commercial
establishments, industrial, and institutional facilities. In this portion of the
group, you will be required to state your arguments or synthesis relevant to
the topics presented. I will answer the first two items, and you will continue
the rest.
1. Population projection is a significant undertaking in demographic
studies. It supplies data on how we are going to plan communities
mindful of the pressing issues on population growth and quality of life.
2. The holistic evaluation of the triggering factors of uncontrolled
population growth, a decline of environmental quality, and scarcity of
resources is deemed necessary to attain sustainable development.
3. DEMOGRAPHIC TRANSITION is a model in which it shows us the
trends of two demographic characteristics (birth rate and the death
rate). this model describes the changes of our population over time.
4. Life expectancy it refers to the number of year a person can expect to
live. In short, it is based on an estimate of the average age at the time
of death of members of a particular population group.
5. A particular way in which absolute inhumanity can grow over a period
of time. It occurs when an amount relating to the time that is
proportional to the quantity itself is changed immediately. This refers
to Exponential Growth.
6. Populations exceed the carrying capacity (K) of their ecosystem as
competition grows and resources become exceedingly limited,
leading their growth rate to slow to almost zero. This smooth S-
shaped curve known as the logistic curve.
7. A constant world and a homogeneous population are expected by
both the exponential and logistic, one under which all persons are
similar in their effects on each other.
8. The pyramid age structure occurs in a population with many young
people and a high death rate at each age—and therefore, it is a high
birth rate, a rapidly growing population, and a relatively short average
lifetime population.
9. There are Five Key Properties of Population namely: abundance,
birth rates, death rates, growth rates and age structure.
