Session 6 2
Session Objectives
Understand major demographic trends in the U.S. and globally.
Understand broad migration trends in the U.S. and globally.
Explore poverty in the U.S. and globally.
Appreciate how population trends can contribute to vulnerability and require special consideration for emergency management and disaster response. Later sessions will explore the relationship between these trends and vulnerability in more detail.

Population & Economic Trends
General trends contributing to vulnerability
– Population trends Population increase Children & Elderly Diversity Migration
– Economic disparity Poverty Access to resources

Session 6 5
Population Growth
Birth Rates: annual # of live births/1000 people Fertility Rates: annual average number of
children a woman has during reproductive years Death Rates = annual mortality rate/1000 Natural increase = Birth Rate – Death Rate

Session 6 6
Implications of Population Growth
Carrying Capacity– Maximum # of individuals of any species that can
be supported by a particular ecosystem on a long-term basis
– Different views: Zero Population Growth: Ehrlich (1970) Bring ‘em on!: Boserup (1965)
Creating stress on resource and land use Living in more marginal environments,
particularly with regard to hazards Changing demographic structure, altering
vulnerabilities

Session 6 11
Migration Implications for Vulnerability
Changing nature of communities– Social and family networks change– Shifting resources
As people move to new places– Often do not have understanding of hazards in
new location Past experiences do not necessarily correspond to
changed geography Limited knowledge about resources & hazards

Migration Trends
Numbers– About 175 million people, or 3% of world’s
population– 60% reside in developed nations
Refugee populations– 15.9 million people in 2000– Most are in developing nations (12.9 million)
Urbanization In U.S., toward the coast

Poverty and Vulnerability
Direct link between poverty and vulnerability Affects access to monetary resources in face
of disaster Impacts ability to mitigate against hazards Must prioritize everyday needs

Income Disparities
Almost one-quarter of the world's 5.7 billion people ''continues to live in a state of severe poverty.'' United Nations
More than 1.3 billion people currently live below the poverty line, surviving on a dollar a day
41 countries designated as "heavily indebted poor countries" by the World Bank, 39 fall into the category of high-fertility nations, where women, on average, bear four or more children. (August 2002)

Session 6 23
UNDP Poverty Report 2000
Two ways of measuring poverty
The $1 per day is an income measure of poverty: it measures the percentage of people who live on less than $1 per day
The Human Poverty Index (HPI)
![Page 24: Root Causes of Social Vulnerability: Demographic and Economic Trends Session 6](https://reader036.vdocuments.us/reader036/viewer/2022062408/5681392e550346895da0d643/html5/thumbnails/24.jpg)
Session 6 24
UNDP Poverty Report 2000
The HPI measures deprivation in basic human development. It takes into account:
– % of people expected to die before age 40– % of adults who are illiterate– % of population without access to health
services– % of population without access to safe water– % of children under five who are underweight

U.S. Home Ownership, 2000
72 percent of non-Hispanic whites 53 percent of Asians 46 percent of African Americans and of
Hispanics. Gap narrowed in recent decades, due in part
to an increasing number of mortgage loans to low-income, minority households

BOTTOM LINE…
hazards impact groups of people differentially based
on demographics and wealthHow do we correct this?
