Target 11.1

By 2030, ensure access for all to adequate, safe and affordable housing and basic services and upgrade slums

Star Star Star Indicator: 11.1.1 Proportion of urban population living in slums, informal settlements or inadequate housing

Migration relevance: Data can be disaggregated by migratory status.

Rationale: Access to adequate housing may be challenging for many migrants, especially irregular migrants.

Data sources: Data for the slum and informal settlement components of the indicator can be computed from census and national household surveys, including DHS and MICS. Data for the inadequate housing component can be computed by using income and expenditure household surveys that capture household expenditures.

Data strengths & limitations

Depending on the source, various strengths and limitations can present when analyzing available data sources for migration.

Statistical sources: These sources, such as censuses, household surveys and labour force surveys, are universal, and allow cross-country comparability; they can also offer detailed data on small population groups. However, depending on the country, surveys might be infrequent and/or costly. Surveys can also present issues with sample size and coverage, and migration questions tend to be left out.  

Administrative sources: Administrative sources can provide detailed and continuous data on small groups. However, visas, residence permits and work permits, while continuous and comprehensive, lack comparable definitions, coverage and availability between countries or ministries within the same country. Furthermore, they often do not cover naturalized citizens or undocumented residents who overstay their visas. It is also important to note that, for example, if a person receives more than one residence permit in a year, or if the permit granted to the head of the family covers his or her dependents, data may not reflect the total number of migrants in the country of residence. 

Innovative sources: Big data sources are timely and provide real-time data; they also have broad coverage and are automatically collected. Some limitations to these sources are that they can be biased and there are privacy and ethical issues with the collection and use of these data.

Data Migration Software

Building out data migration tools from scratch, and coding them by hand, is challenging and incredibly time-consuming. Data tools that simplify migration are more efficient and cost-effective. When you start your search for a software solution, look for these factors in a vendor:

• Connectivity — Does the solution support the systems and software you currently use?
• Scalability — What are the data limits for the software, and will data needs exceed them in the foreseeable future?
• Security — Take time investigating a software platform’s security measures. You’re data is one of your most valuable resources, and it must remain protected.
• Speed — How quickly can processing occur on the platform?

Программа Samsung Data Migration для переноса Windows на SSD

Обратите внимание, что эта программа подойдет только в том случае, если переносить информацию вы будете на новый SSD от компании Samsung. На официальной страничке http://www.samsung.com/semiconductor/minisite/ssd/download/tools.html указаны модели накопителей которые поддерживаются

Там же вы можете скачать последнюю версию программы Samsung Data Migration. А еще там есть очень подробная инструкция на русском языке

На официальной страничке http://www.samsung.com/semiconductor/minisite/ssd/download/tools.html указаны модели накопителей которые поддерживаются. Там же вы можете скачать последнюю версию программы Samsung Data Migration. А еще там есть очень подробная инструкция на русском языке.

Скачайте программу, установите ее, и запустите.

Дальше мы увидим информацию по начальному и конечному диску. Можно изменять размер разделов на новом диске, чтобы распределить между ними всю память.

После того, как вы распределите память между разделами, нажмите на кнопку «Начать».

Осталось только дождаться, пока закончится процесс клонирования на новый накопитель, и можно закрывать программу.

После переноса, я просто заменил старый SSD новым, и у меня компьютер включился как обычно. Только размер разделов стал больше. У меня была установлена Windows 10 как вторая система, и пропал выбор какую систему загружать. По умолчанию загружается Windows 7. Думаю, нужно просто восстановить загрузчик. Пока что этим не занимался.

Если вы оставляете в системе оба накопителя, то нужно просто сменить порядок загрузки в БИОС. Или отключить старый диск.

Data sources

Census and surveys collect migration-related data which can be used to produce official statistics. For example: 

• Censuses produce statistics on migrant stocks, socio-economic characteristics, migrant flows (limited) and some emigration figures. The UN Statistics Division recommends including three core variables in population censuses to identify international migrants. They are: (1) country of birth, (2) country of citizenship, and (3) year or period of arrival in the country for foreign-born persons. 
• Household surveys produce statistics on different aspects, such as the drivers and the impact of migration, internal migration, socio-economic characteristics, emigration, migrant stocks and flows of immigrants and emigrants. 
• Labour Force Surveys produce statistics on migrant stocks in the labour market. 

Administrative sources collect data for purposes other than gathering information on migration, but may be useful in the collection of specific indicators. Statistics derived from data in these sources usually refer to administrative records rather than people. Some examples of sources include: 

• Administrative registers that can potentially produce information on certain groups of persons who change their country of usual residence and thus qualify as international migrants.
• Border data collection systems which produce statistics on flows of nationals and non-nationals entering and leaving through official border posts. 
• Visas, residence permits, and/or work permits that produce statistics on migrant flows and stocks, drivers and impact of migration, and socio-economic characteristics

Innovative data sources—Although the availability of migration statistics from traditional sources is useful to some extent, significant gaps remain, as outlined above. Mobile phones, online tools and platforms, such as social media or online payment services, have become a potentially useful source for migration data. For example:

Big data sources, such as social media and call detail records can produce statistics on migrant flows, drivers and impact of migration, and internal migration.

Information produced by innovative sources includes: migrant flows, drivers and impact of migration, internal migration, public opinion on migration, among others. 

Data sources

Data on diaspora populations are difficult to collect, as emigrants are not automatically members of diasporas, and second- and third-generation descendants of migrants may also be considered or consider themselves to be part of a diasporas group. Generally, there is far more information available on diasporas than there are data. Information is qualitatively different from data, with information suggesting a non-systematic approach. Currently there are no attempts to measure global diaspora populations per se, but the data sources below can act as a proxy for diasporas that maintain links to a certain country of origin. Few data are available on diaspora groups that are linked by a common religion or ethnicity.

Data on emigrant stocks are one such proxy. Many countries report stock data to organizations such as UN DESA, the Organization for Economic Cooperation and Development (OECD) and the Statistical Body of the European Union (EUROSTAT). Some countries with high emigration rates include questions on emigration in their national censuses, which often include questions on emigrant destinations, demographic characteristics, education level, and motivation for migration, among others. However, emigrant stock data give an incomplete picture of diaspora populations, for the reasons listed in the above paragraph, and as global migration figures do not always differentiate between short- and long-term migrants. 

Data on issues relating to diasporas can also inform our knowledge of diasporas. «Brain drain» and related concepts can be measured through data on the education level of emigrants. For example, the OECD measures the education level among migrants in OECD countries and non-OECD destination countries. Similarly, data on migrant remittances capture just one of many ways in which diasporas influence their home and host countries. Current data on diaspora institutions — defined as «formal state offices devoted to matters concerning emigrants and their descendants abroad» — are available in Alan Gamlen´s publication. 

Additionally, operational data can inform our understanding of diaspora groups. For example, IOM’s Migration for Development in Africa (MIDA) programme is a capacity-building programme that promotes the transfer of skills, knowledge, and other resources of African emigrants to their home countries. IOM’s implementation of Return of Qualified Nationals (RQN) and Temporary Return of Qualified Nationals (TRQN) programmes has led to more than 4,000 assignments of diaspora worldwide deploying their skills in sectors such as education, health and technology. IOM has also conducted more than 120 surveys assessing diaspora communities, mostly in OECD member states and European nations. Examples include studies on diaspora groups from Zambia, Angola, Morocco and Moldova. Data from similar programmes, such as the UNDP’s Transfer of Knowledge through Expatriate Nationals (TOKTEN) programme, have been used to assess the effectiveness of diasporas outreach and training programmes in certain countries, such as Sudan and Syria.

How to Plan a Data Migration

Data migration involves 3 basic steps:

1. Extract data
2. Transform data
3. Load data

Moving important or sensitive data and decommissioning legacy systems can put stakeholders on edge. Having a solid plan is a must; however, you don’t have to reinvent the wheel. You can find numerous sample data migration plans and checklists on the web. For example, Data Migration Pro, a community of data migration specialists, has a comprehensive checklist that outlines a 7-phase process:

• Premigration planning. Evaluate the data being moved for stability.
• Project initiation. Identify and brief key stakeholders.
• Landscape analysis. Establish a robust data quality rules management process and brief the business on the goals of the project, including shutting down legacy systems.
• Solution design. Determine what data to move, and the quality of that data before and after the move.
• Build & test. Code the migration logic and test the migration with a mirror of the production environment.
• Execute & validate. Demonstrate that the migration has complied with requirements and that the data moved is viable for business use.
• Decommission & monitor. Shut down and dispose of old systems.

This may appear to be an overwhelming amount of work, but not all these steps are needed for every migration. Each situation is unique, and each company approaches the task differently.

Data strengths and limitations

EU legislation in the migration domain aims to achieve a very high level of data comparability thanks to harmonization as established in the legal basis, and follow-up of EU bodies (Eurostat) of the compliance of Member States. Ease of access to data is another strength, since country statistics can be obtained from a single access point (Eurostat).

In general, migration data in Europe are of good quality, but limitations exist. The analysis of these limitations presented next is a summary of a recent KCMD report. This report looked at migration data gaps from the perspective of EU policymaking, which often is not restricted to events in Europe but have a global scope. The limitations below may therefore refer to data with a European or global coverage. The report identifies four main groups of limitations:

• Gaps in existing data related to timing, quality and disaggregation: EU legislation refers to long term migration data with at least 12 months duration of stay and to immigrations and emigrations events occurred during the reference period of one calendar year t, from 1 January until 31 December of year t. These data are collected by Eurostat annually by 31 December of year t+1 as specified in the legislation and disseminated by February of year t+2. It is clear that with this definition and with the deadline set in the EU legislation these data cannot be available before and may be considered arriving late for policy makers. The EU legislation specifies disaggregations which are mandatory for the countries to provide. Eurostat additionally collects a set of tables on voluntary basis but not all countries provide them. Migration statistics, for example, are not disaggregated by individual countries of previous residence for all reporting Member States, only by broad groups of countries which is the mandatory transmission under the EU regulations. In certain cases, quality of emigration data may be limited because the figures provided underestimate the true dimension of the phenomenon. 
• Dissemination issues: There are various aspects related to the way data are presented to users that may prevent a full exploitation of data. Examples include unclear assumptions or methodologies; this normally refers to situations that are very hard to measure (for instance, internal displacement) and where ad-hoc data collection methods are developed. Another issue relates to what is perceived as reduced visibility of some data; here the challenge is to balance the requirements of a wide range of potential data users, who may be interested in specific tabulations, against the need to preserve an efficient dissemination platform limiting the number of published tables with the same content.
• Data not collected:  Data for some migration topics are not always collected or available, like the educational attainment of refugees, more detailed information on children, or intra-EU mobility of third country nationals.
• Useful data that are currently inaccessible: Data — even if existing — are not always easily accessible. This could be because of legal or commercial terms governing data access, as in the case of some EU Member States’ data held by EU Agencies or new data sources like mobile phone data or social media, privacy concerns, or the need for innovative or laborious analysis of data, as happens with new data sources and surveys.

Categories

Data is stored on various media in files or databases, and is generated and consumed by software applications, which in turn support business processes. The need to transfer and convert data can be driven by multiple business requirements, and the approach taken to the migration depends on those requirements. Four major migration categories are proposed on this basis.

Storage migration

A business may choose to rationalize the physical media to take advantage of more efficient storage technologies. This will result in having to move physical blocks of data from one tape or disk to another, often using virtualization techniques. The data format and content itself will not usually be changed in the process and can normally be achieved with minimal or no impact to the layers above.

Database migration

Similarly, it may be necessary to move from one database vendor to another, or to upgrade the version of database software being used. The latter case is less likely to require a physical data migration, but this can happen with major upgrades. In these cases a physical transformation process may be required since the underlying data format can change significantly. This may or may not affect behavior in the applications layer, depending largely on whether the data manipulation language or protocol has changed. However, some modern applications are written to be almost entirely agnostic to the database technology, so a change from Sybase, MySQL, DB2 or SQL Server to Oracle should only require a testing cycle to be confident that both functional and non-functional performance has not been adversely affected.

Application migration

Changing application vendor—for instance a new CRM or ERP platform—will inevitably involve substantial transformation as almost every application or suite operates on its own specific data model and also interacts with other applications and systems within the enterprise application integration environment. Furthermore, to allow the application to be sold to the widest possible market, commercial off-the-shelf packages are generally configured for each customer using metadata. Application programming interfaces (APIs) may be supplied by vendors to protect the integrity of the data they have to handle. It is also possible to script the web interfaces of vendors to automatically migrate data.

Business process migration

Business processes operate through a combination of human and application systems actions, often orchestrated by business process management tools. When these change they can require the movement of data from one store, database or application to another to reflect the changes to the organization and information about customers, products and operations. Examples of such migration drivers are mergers and acquisitions, business optimization, and reorganization to attack new markets or respond to competitive threat.

The first two categories of migration are usually routine operational activities that the IT department takes care of without the involvement of the rest of the business. The last two categories directly affect the operational users of processes and applications, are necessarily complex, and delivering them without significant business downtime can be challenging. A highly adaptive approach, concurrent synchronization, a business-oriented audit capability, and clear visibility of the migration for stakeholders—through a project management office or data governance team—are likely to be key requirements in such migrations.

Target 10.2

By 2030, empower and promote the social, economic and political inclusion of all, irrespective of age, sex, disability, race, ethnicity, origin, religion or economic or other status

Star Indicator: 10.2.1  Proportion of people living below 50 per cent of median income, by sex, age and persons with disabilities

Migration relevance: Data can be disaggregated by migratory status.

Rationale: This indicator measures «median» income versus indicator 1.1.1 that measures extreme poverty. This indicator is closely related to the social inclusion indicator under the EU Zaragoza Declaration on migrant integration

Data sources: TBD
