The Estimation of Place-to-Place Migration Flows Using an Alternative Log-Linear Parameter Coding Scheme

The log-linear model, with an alternative parameter coding scheme, is used in this paper to obtain estimates of place-to-place migration flows in situations where the data are inadequate or missing. The alternative parameter coding scheme is particularly useful in constructing the origin-destination interaction structure. To illustrate the method, two empirical examples are presented. The first demonstrates the effectiveness of the methodology by estimating known migration flows between states in the Western region of the United States during the 1985-1990 period. The second example focuses on estimating international migration flows in the Northern region of Europe during the 1999-2000 period where the data are incomplete. Both examples demonstrate the usefulness and generality of this particular method for estimating migration flows

An Age-Period-Cohort Database of Inter-Regional Migration in Australia and Britain, 1976-96

Report prepared as part of a collaborative project on "Migration Trends in Australia and Britain: Levels and Trends in an Age-Period-Cohort Framework" funded by the Economic and Social Research Council and the Australian Research Council. This paper describes the way in which parallel databases of inter-regional migration flows for Australia and Britain, classified by five year ages and birth cohorts for four five year periods between 1976 and 1996. The data processing involves estimation of migration data for comparable spatial units, the reduction of the number of those units to a reduced set for ease of analysis, the extraction of migration data from official data files supplied by the Australian Bureau of Statistics and the Office for National Statistics, and the filling of gaps in these files through iterative proportional fitting for some of the British data. The final stage in preparation of the migration databases was to estimate the numbers of transitions (Australia) or movements (Britain) for age-period-cohort spaces. In principle, this last estimation involves a fairly simple interpolation or aggregation of age-time classified migration data, but in practice a great deal of detailed attention is required. A final section specifies the populations at risk to be used for each age-period-cohort observation plan to compute migration intensities

Internal Migration and Regional Population Dynamics in Europe: Romanian Case Study

The report analyses population migration and change in Romania over the period 1984-1994. The analysis of population change is conducted for 2948 communes and towns, the finest administrative division for which population data are available. The lack of migration data on the level of communes and towns makes in-depth analysis of the migration for small spatial units impossible. For that reason analysis of the patterns of migration is conducted for 40 Judete (also referred to as counties or regions) and the capital city of Bucharest, i.e. 41 units altogether.

Information on bird navigation obtained by British long range radars

Radar observations of the migratory habits of passerine birds over a 10 year period are presented. The relationships between intensity of cloud cover and the frequency and density of migration are illustrated. The aspects of migration which were determined by the radar were: (1) migration under total overcast, (2) compensation for wind drift, (3) changes in flight direction during migration, and (4) effects of meteorological parameters

Russian Migration Policy and Its Impact on Human Development

For Russia, migration policy – in terms of internal or/and international migration flows management – was an ever-important element of the State activities. Concentrated on State interests, the policy also resulted in human development. The paper presents a historical overview of the Soviet and Russian migration policies with special emphases on the impact on human development and the driving forces behind the changing policies. The Soviet period can be characterized as contradiction between strict limitations on the freedom of movement provided by the propiska system, and large-scale population movements, both voluntary and involuntary, that were inspired by economic and administrative policy measures to meet labor demand of an industrializing economy. In the post-Soviet period, international migration is the major focus of the Russian migration policy. The Russian Federation is the major receiving country in the vast former USSR territory. The evolution of Russian migration policy in the post- Soviet period is a good example for getting a better understanding of how the everlasting conflict between the need for additional human resources and anti-immigrant public moods (typical of all receiving countries), combined with the opportunistic considerations of political elites, that hampers the elaboration of a reasonable long-term migration strategy. Russian migration policy has been drifting from a relatively open immigration regulation based on a laissez faire approach in the early 1990s to restrictive immigration laws in the early 2000s and to an ‘open door’ migration policy in respect to CIS citizens in 2007.Human development, internal migration, international migration, migration policy, Russia

Structure of Demographic Types of Small Towns in Poland Spatial and Temporal Approach

The aim of this paper is to determine changes in the structure of demographic types of small towns in Poland between 2004 and 2013. It is assumed in the paper, following the Central Statistical Office of Poland, that small towns are urban settlements having less than 20,000 inhabitants. The time period covered in this study is the time of Poland’s accession to the EU, which brought reduction of many barriers on the labour market and in migration movement. Demographic types of small towns were determined using Webb’s typology. Natural increase and migration indicators constitute its base. It was found that the share of towns of progressive character decreased and the share of those of regressive character increased in the analyzed period. A negative migration balance had the greatest effect on the number of inhabitants of the analyzed settlement units. The described demographic changes in small towns in Poland were connected with the second stage of demographic transition

Seasonal migration and micro-credit in the lean period : evidence from northwest Bangladesh

This paper investigates the relationship between access to micro-credit and temporary seasonal migration, an issue which is largely ignored in the standard rural-urban migration literature. Seasonal migration due to agricultural downturns is a common phenomenon in developing countries. Using primary data from a cross-sectional household survey from the northwest part of Bangladesh, this study quantifies the factors that influence such migration decisions. Among other results, we find that network effects play a significant role in influencing the migration decision, with the presence of kinsmen at the place of destination having considerable impact. Seasonal migration is a natural choice for individual suffering periodic hardship; however the strict weekly loan repayment rules of Micro-credit Institutes can have an adverse effect on this process, reducing the ability of borrowers to react to a shock. Our result suggests that poor individuals prefer the option of not accessing the micro-credit and opt for temporal seasonal migration during the lean period. The results have numerous potential policy implications, including the design of typical micro-credit schemes.Bangladesh, Microfinance, Population movement, Lean period, Seasonal migration, Micro-credit

No. 27: Migration and Development in Contemporary Mauritius

Mauritius is a society descended of involuntary and voluntary migrants. After two-and-a-half centuries of settlement as a plantation colony and by the time of its independence from colonial rule in 1968 the island nation’s population had grown to seemingly insupportable levels. But having faced the afflictions of overpopulation, social division and economic despair (and sizeable emigration) at the dawn of its independence, it took just a decade and-a-half for despondency to fade and for Mauritius to begin resembling a tropical idyll of sorts. Though poverty persisted as the small island successfully transformed its economy from colonial plantation to mostly industrial (light manufacturing) and service (tourism and financial services) activity, rapid economic growth became a normal condition and living standards improved markedly under conditions of parliamentary democracy. If the threat of overpopulation had initially hung over the fledgling republic, the subsequent period of prodigious economic growth saw a vast expansion of formal employment and a decimation of unemployment. During this growth spurt the Mauritian economy resumed its reliance on contractual labour migrants from abroad. Contemporary Mauritius enjoys a reputation of developmental success and it is frequently held up as a model to be emulated by other aspiring developers. While the last quarter of a century of this success coincides with a phase of systematic and unabated contractual labour migration, the Mauritian government has more recently embarked on further migration schemes, on the one hand to attract highly qualified and ‘high net worth’ individuals to the country and on the other hand to encourage circulatory out-migration. Both the decades-old system of contractual labour migration and these more recent movements are closely aligned with the country’s development trajectory, providing a test of widely-held assumptions about the relationship between migration and development. Focusing mainly on international labour migration, and viewing it within the context of a global division of labour, this policy brief provides an account of migration and development in contemporary Mauritius. The first part deals with conceptions of the migration and development relationship, the second introduces current patterns of migration into and out of Mauritius, the third examines labour migration to Mauritius, and the final part offers some conceptual and policy-related generalisations arising from the study of the migration-development relationship in Mauritius. Concentrating on the period 2005 to 2010 and focusing especially on the migration of clothing and textile factory workers, the study relies primarily on official statistics and media reports for its empirical content and it draws also from published and organisational sources

Gene-flow between populations of cotton bollworm Helicoverpa armigera (Lepidoptera: Noctuidae) is highly variable between years

Both large and small scale migrations of Helicoverpa armigera Hübner in Australia were investigated using AMOVA analysis and genetic assignment tests. Five microsatellite loci were screened across 3142 individuals from 16 localities in eight major cotton and grain growing regions within Australia, over a 38-month period (November 1999 to January 2003). From November 1999 to March 2001 relatively low levels of migration were characterized between growing regions. Substantially higher than average gene-flow rates and limited differentiation between cropping regions characterized the period from April 2001 to March 2002. A reduced migration rate in the year from April 2002 to March 2003 resulted in significant genetic structuring between cropping regions. This differentiation was established within two or three generations. Genetic drift alone is unlikely to drive genetic differentiation over such a small number of generations, unless it is accompanied by extreme bottlenecks and/or selection. Helicoverpa armigera in Australia demonstrated isolation by distance, so immigration into cropping regions is more likely to come from nearby regions than from afar. This effect was most pronounced in years with limited migration. However, there is evidence of long distance dispersal events in periods of high migration (April 2001–March 2002). The implications of highly variable migration patterns for resistance management are considered.K.D. Scott, K.S. Wilkinson, N. Lawrence, C.L. Lange, L.J. Scott, M.A. Merritt, A.J. Lowe and G.C Graha
