CHAPTER VII CONCLUSION AND RECOMMENDATION
Key Research Questions
(i) Who migrates? Are the food insecure households more
prone to migration?
(ii) What are the different types of migration including child
migration?
(iii) Are the rural-urban migration flows concentrated towards
some big cities only?
(iv) Is the food security status of migrant households different
from that of non-migrant households and how?
(v) What are the Asian evidences and policy implications of
rural- urban migration associated with food security?
(vi) What is the impact of migration on food security status at
origin?
(vii)What strategies are to be taken to optimize the rural-urban
migration outcome to food security?
Objectives and Expected Outputs
Objectives
• To sharpen policy-makers’ understanding of the diversity of rural to
urban migration strategies and their impacts on household and
individual food security in sending and receiving areas,
• To provide information on potential interventions to strengthen
migrant household food security.
Expected Outputs
(i)Identification of migration diversity through exploring the typology
and mapping of its patterns,
(ii)Determination of food security status of the migrant households and
impact of migration on their food security,
(iii)Review of Asian literature to find out evidence on the association of
food security, rural urban migration and poverty reduction,
(v)Formulation of intervention to address food security of migrant
households.
Data and Methodology
The study has adopted following techniques to gather the primary data:
• Household-level survey at origin
• Tracer survey at destination
• Focus Group Discussion (FGD)
• Key Informant Interview (KII)
In addition, the study has analyzed the HIES-2010 and Panel data of Dr.
Mahbub Hossain to compare the relevant findings of the survey data.
Sample Design for Household Level Survey & Tracer Survey
• The study provided the main Indicators in 2 rural domains, according to the
East-West divide reported by the World Bank study of Bangladesh
• The sample size determination formula yields that 750 migrant households
are required to cover in each domain.
• The study has adopted cluster (PSUs of BBS) sampling and covered 30
clusters in each domain (using systematic PPS)
• Ultimately, 3000 units of analysis have been covered:
- 1500 Migrant and 750 Non-migrant households at origin
- 500 Migrant and 250 Non-migrant households under Tracer survey
Analytical Techniques
Step-1: Measure the flow of migration including selectivity
The flow of rural-urban migration has been explored through
descriptive statistics in different dimensions including flow-mapping.
Step-2: Measurement of the status of food security
(i) Perception analysis; (ii) Direct calorie intake (DCI);
(iii) Food expenditure; (iv) Coping strategy index (CSI) score
Step-3: Identification of the predictors of food insecurity
The binary multiple logistic regression model (BLRM) has been
applied to identify the predictors of food insecurity.
Step-4: Impact of migration on food security
The impact of migration on food security at origin has mainly been
studied using 2-stage and 3-stage NELM models
In particular, instrumental variable (IV) regression has been employed
to study the impact of migration on per capita calorie intake.
The similar model has also been used by simultaneous consideration
of migration determinants, remittance behaviors and income.
2-Stage NELM Models
Where FS measures the per capita calorie-intake as a proxy food security status
at the household level; Mig measures the number of migrants per household; X
vector encompasses the household characteristics; Z is a vector of instruments
3-stage NELM Models
The basic equation for household income, (as a proxy of household food
security) according to the NELM hypothesis can be expressed as
Y c k  ok  1k M   2k R  3k Z k   k k = on-farm, off-farm;
R   o  1M   2 Z R   R
M  f ( ; Z M )   M
where
f ( ; Z M )  exp(0  1Z M )   M
To model migration, this study considers using count regression functional form,
particularly the Poisson distribution form, since the number of migrants is nonnegative.
Concluding Remarks from Review of Asian Evidence
Migration Pattern/Diversity/Causes:
- Mainly young people strive for migration
- Migration is higher from environmentally fragile areas
- Increasing trend of temporary and circular migration
- Feminization of internal migration
- Concentration of migration towards big cities
- Major causes of migration are wage differentials, population pressure etc.
Positive Impact At origin:
-Poverty reduction & gain of assets
- Human resource development
- Food security at household level
- Women empowerment
- Fertility control
- Change in family composition
Negative Impact At origin:
- Labor depletion in a few cases
- Loss of agricultural productivity
- Family disintegration
-Increase of women and children
chores
Positive Impact at Destination:
- Urban growth
- Availability of workers for urban services
-Availability of manpower for industry,
particularly manufacturing, development sector
Negative Effect at Destination:
- Unplanned urbanization
- Growth of slums
- Environment pollution
- Ultimately, ill consequences on transport,
healthcare & other service sector
General Features of the Study Population for RUM-2012 Survey data
 About 29.2% study population were below 15 years of age, about 66%
fell 15-64 years and about 4.4% were of 65 years or above.
 Approximately 21% of the adult men earned incomes from agriculture,
about 22% were unemployed, 12.6% engaged in study and the rest
earned from off-farm activities. On the contrary, three-quarters of the
women were engaged in household work, 9% engaged in study, about
11% were engaged with agriculture.
 About 21% of the study population aged 5 years or older was found to
have no education, about 36% were found to have primary-level
education, about 39% were found to have secondary/higher secondary
level education and only 5% people attained graduate level education.
 The analysis of housing condition, sources of water & lighting and
sanitation facilities as well as asset score of the surveyed households
according to the migration status indicates that the migrant-households
are better positioned than their non-migrant counterparts in terms of
housing condition and possessing wealth.

CONCLUSIONS
•In rural Bangladesh, over half of the households are functionally landless
and the migrant-households are economically better positioned.
•Internal migration flow is higher from the West and international migration is
higher from the East.
• Food insecure or poor are not more prone to migration.
•The migrants tend to concentrate to capital city and district headquarters.
•The young people (aged 15-29 years), males and sons/daughters of the
household heads are more exposed to rural-urban migration.
•Temporary migration dominates over other types of migration and
independent/single migration over family migration.
•Literate people are more prone to permanent migration and illiterate people
are more prone to temporary migration.
•Type of migration from food insecure households significantly differs from
that from food secure households.
•Poverty, unemployment and poor educational facilities are found out as the
main push factors. In contrast, better employment opportunities, better
schooling, and wage differentials are sorted out as the main pull factors.
Cont…
•About three-fifths of the migrants sent remittances (average amount of
Tk.38397) and household heads mainly decide to utilize remittances.
•All the estimates of food insecurity indicate that non-migrant households
are more vulnerable to food insecurity. The estimates also show that the
migrants at destination are significantly less food insecure than their origin
counterparts.
•Reliance on less preferred and less expensive food items and purchase of
food on credit are explored as the top coping strategies of food insecurity.
•Landholding, occupation and education of the household head, debt status,
location, dependency ratio, family size and household headship are
determined as predictors of household level food insecurity.
•Perception-based estimates on change pattern of some socioeconomic
indicators reveal that migration puts mixed impact with positive net
impact.
•NELM-models determine that rural-urban migration exerts significantly
positive impact on food security through different dimensions.
•The major findings covered by the review of Asian literature are
corroborated by the findings of the present study.
Recommendation
•Improve educational facilities for quality education in rural areas, which
matches the skill needs of rural labour markets including vocational and
training facilities.
•Promote programmes to enhance more and better opportunities for
employment and entrepreneurship development in rural Bangladesh to
provide alternatives to distress rural-urban migration, especially for youth.
•The Government should also invest in better labour market information
systems and job information services so that youth can access to better jobs
and undertake migration in a more informed manner.
•Actions to prevent and eradicate child labour, especially its most hazardous
forms, with particular attention to unaccompanied child migrants.
•Decentralize both administrative and developmental activities to discourage
the concentration of rural-urban migration to capital city in particular and
other big cities in general.
•Local government should make proper arrangements for safety and security
in rural areas for a sound environment to make rural stay hassle and anxiety
free to discourage rural-urban migration and encourage reverse migration.

Overall Message of the Study
The study explores that different kinds of adversity at origin compel a
stipulated section of rural population to strive for migration to urban
end where different kinds of prosperity attract them.
Different impact determining analyses based on descriptive,
perception-based and model-based estimates identify that impact of
rural-urban migration is significantly positive on food security in
particular and overall living condition in general.
The majority of the findings of the present study are found to be
aligned with those extracted from the review of literature, particularly
on Asian countries.
One final message is that since migration is a revealed preference of
the migrants, it cannot be stopped; rather, the policy-makers can
make policies to better manage migration flows by providing support
to leverage the opportunities arising from migration and remittances.
