Filling the 'migration gaps' - Can research outcomes help us improve migration statistics?

Dec 1, 20161 like176 views

This document discusses using research outcomes to improve migration statistics by filling data gaps. It summarizes a decade of EU-supported migration research projects proposing consistent estimation methods. While methods are formally endorsed, limitations include technical skills, maturity of methods, and risk of inconsistent estimates. Options discussed include using estimates for validation, analysis, or adjusting official statistics, but challenges remain in operationalizing estimates. The document argues the need for continued progress in bridging the gap between statistics and research to better measure migration.

The document analyzes GPS tracking data from 17,000 private vehicles in Milan, Italy over the course of one week. It finds that: 1) Traffic patterns followed consistent daily and weekly trends, with more traffic during weekday commuting hours and less on weekends. 2) Trip lengths and durations followed power law distributions, with many short trips and few long trips. 3) Traffic was concentrated in the city center during early morning and late evening hours, and dispersed to other areas during daytime commuting periods. 4) Clustering trips by route identified groups that took direct and indirect routes between origin and destination points like the city center and northwest areas.

Outcomes researchJulie Hussey

Outcomes research seeks to understand the end results of health care practices and interventions, including effects on quality of life and mortality. It links the care received to outcomes experienced to improve quality. Outcomes can be grouped as care-related, patient-related, or performance-related and are measured over short, intermediate, and long terms. Agencies like AHRQ and PCORI fund outcomes research to establish evidence-based practices and evaluate care quality. PCORI's mission includes increasing research quality and speeding evidence implementation to influence funded research.

Week 12 ppt researchShalee Belnap

Outcomes research examines the end results of health services on individuals and is intended to provide scientific evidence to inform healthcare decisions. It consists of clinical studies of expanded patient outcomes as well as studies of populations, databases, and healthcare delivery systems. Outcomes research identifies types of outcomes like care-related, patient-related, and performance-related outcomes, and is typically quantitative rather than qualitative. It assists in evidence-based practice, evaluates delivered care, measures innovation effectiveness, and is important due to rising costs, standards, and public reporting. Factors to consider in determining outcomes include patient populations, team members, organizational priorities, and mandated reporting.

This document defines and classifies different types of outcomes in healthcare research. It discusses short, intermediate, and long-term outcomes as well as care-related, patient-related, and performance-related outcomes. Positive outcomes in patient-centered outcomes research aim to incorporate diverse participants and address individual needs and preferences related to survival, function, and quality of life. Negative outcomes can occur when industry sponsors clinical research, introducing potential bias favoring their products. Proper outcomes measurement involves determining measures of interest, gathering data, analyzing results, interpreting outcomes, making changes, and remeasuring to evaluate effectiveness.

This document provides guidance on conducting health economics and outcomes research (HEOR) initiatives to evaluate a pharmaceutical brand's care and cost performance. It recommends starting with an internal and external assessment of the brand to identify information needs, then conducting a pilot analysis using claims data to refine objectives and methodology before embarking on a full-scale "Deep Dive" analysis. Key steps include engaging stakeholders, establishing core metrics, validating results through advisory boards, and applying findings to strengthen the brand's position and value proposition. The overall goal is to generate meaningful insights about a brand's real-world care and cost attributes.

Measuring migration a statistical challengeGiampaolo Lanzieri

Giampaolo Lanzieri discusses the challenges of measuring migration statistics. Defining who is a migrant and what constitutes their country of usual residence is difficult given different circumstances like temporary travel or multiple residences. Migration data can measure either stocks (population counts) or flows (number of migration events), but sources often disagree. Identifying migration requires considering factors like border crossings, stay duration, residence concept, and migration purpose. Certain groups like circular or irregular migrants further complicate measurement. Over time, estimates and statistical models have increasingly supplemented traditional counts to better measure this complex phenomenon.

Giampaolo Lanzieri from Eurostat presented statistical facts and tools for monitoring preparedness for demographic changes in the EU. He showed that migration has overtaken natural population change as the main driver of population growth in the EU. By 2050, migration could increase the total EU population by over 50 million people compared to without migration. However, EU populations are also aging rapidly. Lanzieri discussed challenges like population decline, aging, and integration and presented indicators and tools like the Active Aging Index and Migrant Integration Policy Index that can help monitor preparedness for these challenges. He proposed that combining different indicators could provide an aggregated measure of preparedness across member states.

Giampaolo Lanzieri - europes demographic projectionsMigrationPolicyCentre

This document discusses demographic challenges facing the EU and tools for monitoring preparedness. It provides statistics on migration flows and stocks in the EU. Over the past 50 years, migration has overtaken natural population change as the main driver of population growth. The EU population is aging rapidly and becoming more diverse due to migration. Several monitoring tools are highlighted that measure preparedness for issues like aging, integration, and labor supply shortages. The document argues for developing aggregated measures of preparedness to better understand differences between countries. Examples of hypothetical indexes are presented to illustrate how monitoring tools could be combined.

This document discusses a framework developed by the UNECE Task Force for measuring the socioeconomic integration of migrant populations over time. It focuses on foreign-born individuals and their children (the second generation). A longitudinal approach is proposed to understand how migrant groups' characteristics and conditions change with duration of residence. Examples of relevant indicators are provided across various dimensions like education, social engagement, labor market outcomes, and health. Challenges of data collection and limitations of current sources are also noted. Next steps include further defining indicators for other dimensions, reviewing existing data sources, and developing guidance for countries.

This document discusses Italy's strategy for transitioning from a traditional decennial census to a continuous census model that integrates statistical and administrative data. It describes Italy's 2011 census which first began combining census data and administrative records. Experimental surveys in 2015 further tested registering the population based on administrative records supplemented by sample surveys. The goal is a continuous census system that uses statistical registers built from integrated administrative data sources and sample surveys to regularly update and estimate population counts and characteristics.

Monitoring Internal Migration in the United KingdomUKDSCensus

Internal migration in the UK saw modest declines in intensity from 2000-2001 to 2010-2011 according to census and administrative data, with the largest decreases for those aged 45-59. Inter-district migration distances also decreased slightly. When compared internationally, the UK's aggregate migration intensity was average. The document advocates for greater use of origin-destination census data, cross-national migration research, and consideration of scale and zonation effects in internal migration studies.

The document discusses labor mobility in the European Union following the 2004 and 2007 enlargements. It analyzes migration flows between newer EU member states (EU-8 and EU-2) and older member states (EU-15), finding that over 1 million people from EU-8 countries and over 400,000 from EU-2 countries migrated to EU-15 states. The document also examines the impact of this increased labor mobility on host and home economies, though the effects varied between countries based on the size of migration flows relative to population. Descriptive statistics and three figures are presented on migration stocks between the EU country groups from 2003-2009.

Economic research on diversitydiversityforum2011

This document summarizes a presentation about economic research on diversity through international migration. It discusses several topics covered in the research, including measuring diversity through indexes, the impact of migration on wages and employment, productivity and innovation, and trade. It notes that research finds diversity has a small but positive impact on wages and employment, and that among firms that hire skilled immigrants, greater diversity of foreign workers enhances product innovation. Meta-analyses show an increase in the number of immigrants increases trade volumes by around 1-2%. The presentation concludes by discussing the relevance of this research for policies in New Zealand.

CASE Network Studies and Analyses 359 - Labor Migration: Macroeconomic and De...CASE Center for Social and Economic Research

In this paper, we assess the demographic and economic consequences of migrations in Europe and neighbourhood countries. In order to do so, we rely on a multi-region world overlapping generations model (INGENUE2). The rich modeling framework of this multi-regions model allows us to put into connection migration with the "triangular" relationship between population aging, pension reforms and international capital markets. With this model, we are also able to quantify the demographic and economic consequences of migration ows on both the regions receiving and losing migrants. Our analysis is based on a very detailed migration scenario between Western Europe and the Neighborhood regions constructed by taking into account both the current situation and some prospective empirical scenarios. Our quantitative results shed some light on the long term consequences of migration on regions that are not at the same stage in the ageing process. Concerning the regions receiving migrants, despite some improvement of their public pension system, it appears that our realistic migration scenario does not offset the effect of ageing in these regions, leaving room for pension reforms. Concerning the regions losing migrants, the adverse economic consequences of emigration appear to be all the more important than the region is advanced in the ageing process (and is already suffering from a declining population).

1) The integration of immigrants should be measured by both disadvantage (differences in outcomes between immigrants and natives) and penalty (differences that remain after controlling for personal characteristics). 2) Longitudinal data is needed to properly evaluate integration over time, but such data is lacking in Italy. Cross-sectional data using "years since migration" as a proxy is flawed. 3) Differences in living conditions between families with all immigrants and mixed families were surprisingly small, raising questions about composition effects.

Estimating Migration Flows Using Online Search Data - Project Overview UN Global Pulse

This study was conducted in partnership with the United Nations Population Fund (UNFPA) to explore how online search data could be analysed to understand migration flows. Using Australia as a case study, Google search query data from around the world was disaggregated by country and compared to historical official monthly migration statistics provided by UNFPA. Correlations were observed between relevant search queries (for example, searching for ‘jobs in Melbourne’) and official migration statistics (number of people who migrated to Melbourne). In particular, queries from specific locations in Australia related to local employment opportunities showed highest correlation. The research findings point toward new possibilities for further exploration into using online and other digital search data as proxy for migration statistics.

How to Set Up Process Mining in a Decentralized Organization?Process mining Evangelist

The history of a.s.r. begins 1720 in “Stad Rotterdam”, which as the oldest insurance company on the European continent was specialized in insuring ocean-going vessels — not a surprising choice in a port city like Rotterdam. Today, a.s.r. is a major Dutch insurance group based in Utrecht. Nelleke Smits is part of the Analytics lab in the Digital Innovation team. Because a.s.r. is a decentralized organization, she worked together with different business units for her process mining projects in the Medical Report, Complaints, and Life Product Expiration areas. During these projects, she realized that different organizational approaches are needed for different situations. For example, in some situations, a report with recommendations can be created by the process mining analyst after an intake and a few interactions with the business unit. In other situations, interactive process mining workshops are necessary to align all the stakeholders. And there are also situations, where the process mining analysis can be carried out by analysts in the business unit themselves in a continuous manner. Nelleke shares her criteria to determine when which approach is most suitable.

Today's children are growing up in a rapidly evolving digital world, where digital media play an important role in their daily lives. Digital services offer opportunities for learning, entertainment, accessing information, discovering new things, and connecting with other peers and community members. However, they also pose risks, including problematic or excessive use of digital media, exposure to inappropriate content, harmful conducts, and other online safety concerns. In the context of the International Day of Families on 15 May 2025, the OECD is launching its report How’s Life for Children in the Digital Age? which provides an overview of the current state of children's lives in the digital environment across OECD countries, based on the available cross-national data. It explores the challenges of ensuring that children are both protected and empowered to use digital media in a beneficial way while managing potential risks. The report highlights the need for a whole-of-society, multi-sectoral policy approach, engaging digital service providers, health professionals, educators, experts, parents, and children to protect, empower, and support children, while also addressing offline vulnerabilities, with the ultimate aim of enhancing their well-being and future outcomes. Additionally, it calls for strengthening countries’ capacities to assess the impact of digital media on children's lives and to monitor rapidly evolving challenges.

The challenges of using process mining in internal auditProcess mining Evangelist

Euroclear has been using process mining in their audit projects for several years. Xhentilo shows us what this looks like step-by-step. He starts with a checklist for the applicability of process mining in the Business Understanding phase. He then goes through the Fieldwork, Clearance, and Reporting phases based on a concrete example. In each phase, Xhentilo examines the challenges and opportunities that process mining brings compared to the classical audit approach. For example, traditionally, the analysis in the Fieldwork phase is based on samples and interviews. In contrast, auditors can use process mining to test the entire data population. In the Clearance phase, process mining changes the relationship with the auditee due to fact-based observations.
