28 Catalogue of Indicators Demography TFP=Total female population 3.) RMM=Rate of local male migrant; NMCR=Number of local male population change residence; TMP=Total male population Priority: Yes Indicator developed: Yes Local/International: International Kind of indicator: On going Data source/s: Population Census. Cambodia Inter-­‐Censal Population Survey. Challenges: [1] The definitions of immigrant and emigrant used by different countries and even for different data sources within a single country vary considerably, thus compromising the comparability and interpretation of the indicator. The data are often poorly measured restricting the usefulness for modelling purposes. Illegal immigrants are not captured by the census or survey statistics. Linked to policy: Millennium Development Goals Other comments: [1] Net internal migration rate: Censuses are the major source of Information on internal migration. They vary, however, in the type of data they collect and the way in which the information obtained is coded and tabulated. The questions most commonly included in censuses that indicate the occurrence of some change of residence are: current place residence and place of residence at a specific time before the census; current and previous place of residence, and length of stay in current residence; place of birth. Most countries code place of residence in terms of major geographical subdivision (state, department, province etc.) although use of a finer subdivision of the territory is often useful. Some countries record the urban or rural nature of the place of residence involved. However, net rural-­‐urban migration is more likely to be derived from indirect estimation procedures than directly from census data. In general, data on internal migration gathered by censuses remain underexploited and there is no comprehensive source of information of net migration rates between different units within countries, except for countries with a population register. Other indicators of migration such as the percentage of the population born outside the country (a "stock" measure) are often used instead of the net migration rate. This indicator can also include the next categories: rural to rural, rural to urban, urban to rural and urban to urban. Data by province is available too.
