TOPICS AND SUBTOPICS: (first draft)

1. Basic Outlines of Migration

Migration comprises a foundational unit of the study of any population. Measured in conjunction with births and deaths, migration into and out of any place determines the ultimate size of the population. Migration is a specialized form of moving that involves distinct components of distance, duration and residence. Conceptually, migration is often differentiated into internal and international flows. Internal migration historically has consisted in large part of continued urbanization of a previously rural population, but it may also show counterstreams moving from cities to suburbs.

International vs. internal

• Distance and activity space, duration, and national versus local boundaries.

• Change in circulation
• Partial vs. total displacement migration

• International as product of Westphalian system of nation-states

• Growth of regulation in 20^th century
• Growth in typologies of migrants
• Diasporas may exist without nation-state identification

Kinds of migration

• Primitive, or nomadic
• Voluntary, or agent-based, within large groups or clans or small-scale, as individuals or households

• Authorized, legal, documented
• Unauthorized, illegal, undocumented; "aliens"

• Involuntary, or forced, impelled.

• Displacement, warfare; environmental degradation and disaster
• Human trafficking, slavery
• Refugees, asylees

• Circular, or returning migration, sojourner vs. settler
• Step migration

Non-migration

• International: students, tourists, business travelers; foreign-born vs. immigrants
• Internal: Recurrent movement (commuting, daily crossings, seasonal work)

II. Measurement of Migration and Statistical Methodology

This topic covers the general demographic and statistical concepts underpinning migration research. Initially, migration research followed a standardized set of concepts and measurements derived from demographic research and often dependent upon the geographical units within which data are collected. However, the research has expanded into multiple fields with many methodologies, both qualitative and quantitative.

Demographic concepts

• Flows vs. stocks

• Areas of origin and destination
• Emigration and immigration
• Differential migration

• Gross and net migration
• Components of change (residual) estimation; forward survival.
• Status and propensity rates, probabilities, in-migration, out-migration rates, net migration
• Estimates and population projections
• Distance, distance decay, gravity models
• Efficiency: ratio of streams to counterstreams
• Migration histories

Economic and sociological models

• Econometric models and general models of inequality, within and between cities or countries
• Multivariate regression analysis
• Ethnographies

Spatial analysis

• Geographic Information Systems, with database of attribute information, boundary files, digital map layers, analysis tools and user interface.
• Political and data units: e.g. wards, counties, metropolitan areas, states, provinces, nations

III. Migration Data

Migration data vary widely across countries, both in terms of scope of collection and basic understanding of the definition of migration. This section examines the types of data collection instruments and their components.

Censuses

• Frequency, coverage, de facto vs. de jure, usual residence, field checking, coverage error and content, net and differential undercounts, continuous measurement, migration questions, dual-system estimation, demographic analysis
• Types of files and unit coverage: e.g. region, division, state, county, minor civil division/townships, places, census tracts, block groups, blocks.

Administrative records

• Population registers, universal and partial; ports of entry and/or exit, passports and visas issued, immigration yearbooks, tax records, social welfare/security records, city directories, postal stops, school enrollments, construction permits, utility usage.

Surveys

• Sampling issues, sample bias, panel studies, attrition.

Other sources

• Naturalizations and change of migration status
• Apprehensions and deportations; denaturalizations
• Asylee petitions, United Nations High Commissioner for Refugees

V. Migrant Selectivity

Particular types of people are more likely to migrate than others. This section describes these typologies and the theoretical and practical considerations of migrants.

Adjustment causes vs. induced causes of residential mobility (Clark)
