All census samples extend pre-existing series for those countries. \n--91 quarterly labor force surveys from the Philippines (1997 - 2019) were added to IPUMS.\n\nSUPPLEMENTAL DATA.\n\n--No \"supplemental data\" listed in revision history\n\nNEW VARIABLES.\n\n--New spatially harmonized birthplace and previous-residence variables are available for samples in this data release. More information is available here (https:\/\/international.ipums.org\/international\/geo_mig.shtml). \n--Users should note that many older migration and birthplace variables are available by different names. Refer to this table for a crosswalk of old and corresponding new migration variables. For birthplace variables refer to this table (https:\/\/international.ipums.org\/international\/resources\/misc_docs\/migCrosswalk_names.pdf).\n\nEDITED SAMPLES.\n\n--For the Zambia 2000 sample, an error in the household breaks was corrected, resulting in the creation of 1,988 new households (1% increase) that were previously combined with other households. The person records included in the sample did not change. Due to an inconsistency in the original file, no household-level information other than geographic location is available for these newly identified households, necessitating the addition of \"unknown\" values for this sample to the following variables: BEDROOMS, ELECTRIC, FLOOR, FUELCOOK, FUELHEAT, OWNERSHIP, PHONE, RADIO, REFRIG, ROOMS, SEWAGE, TRASH, WATSRC, TV, TOILET, GQ, ROOF, WATSUP, BIKE, MOTORCYCLE, KITCHEN, GQTYPE, AUTOS, and WALL.\n\nEDITED VARIABLES.\n\n--For the 1998 and 2008 Malawi samples, the family interrelationship pointer variables MOMLOC and POPLOC were modified to allow a \"Spouse\/partner\" of the household head to be linked as a parent to an \"Other relative\", because the enumeration instructions specify that adopted and stepchildren were categorized as \"Other relative\". These samples are now consistent with the links made in the newly released 2018 Malawi sample, which had the same enumeration instructions for adopted and stepchildren.\n--In the samples for C\u00f4te d'Ivoire 1988 and 1998, Rwanda 1991 and 2002, Togo 1960 and 2010, and South Africa 2001, for the harmonized variable POLYGAM, persons in consensual unions were previously coded as \"No, in monogamous union\". Because there was no response option in these samples for polygamous consensual unions, it is more appropriate to treat these cases as not-in-universe, so they have been recoded to \"NIU (not in universe)\".\n--MARST has been edited for Honduras 1974 to reclassify the source variable responses \"married, wife lives separately\" and \"consensual union, companion lives separately\" as separations. The documentation suggests that \"separately\" actually indicates a relationship separation and not an absent spouse or companion. Other minor edits were implemented for MARST for Mozambique 1997 and 2007.\n--In the Mozambique 1997 sample, an error was corrected that recoded persons with a relationship of \"Unknown\" in the source data to \"Other relative or non-relative\" (6000) in the harmonized variable RELATE. These persons are now coded as \"Not Stated\/Unknown\" (9999).\n--In the Malawi 1987, 1998, and 2008 samples, for variable WATSUP, a programming error was corrected such that any households who reported having piped water in either the wet or the dry season are classified as having access to piped water. This programming was also applied to the newly released 2018 sample.\n--The NATIVITY variable has been edited in the Chile 2017 sample to correct a programming error that mistakenly classified as foreign-born about 20 thousand person records that were actually native-born.\n--The MIGRATE5 variable has been edited in the Chile 2017 sample, given a programming error that classified most migrants as having changed their major geographic unit. The MIGRATE5 variable for the Chile 1982 and 1992 samples has been edited to use spatially harmonized geographic units to calculate migration status.\n--In the 1989, 1999, and 2009 Kenya samples, households who indicated that their lighting type or fuel was \"Solar\" were recoded from \"No\" to \"Yes\" in ELECTRIC, based on secondary sources documenting the spread of home solar energy systems in Kenya beginning in the mid-1980s. In the 1989 and 1999 Kenya samples, programming was removed that previously recoded households that reported using electricity as their main cooking fuel to \"Yes\" in the access to electricity variable ELECTRIC, making it more consistent across samples. Other minor edits were implemented for ELECTRIC in Botswana 2011, Ethiopia 1984 and 1994, Mongolia 1989, Mozambique 2007.\n--Some samples in DISCARE classified responses indicating \"some\" difficulty into \"yes\". These cases were revised to consistently include in \"yes\" only responses indicating \"a lot of difficulty\" or \"cannot do at all\".\n--Some codes were improperly labeled for municipalities in Honduras 1961 and 1974, which affect variables on place of residence, birthplace, and previous residence."}},"study_desc":{"title_statement":{"idno":"PAK_1981_PHC_v01_M_v7.6_A_IPUMS","title":"Housing and Population Census, 1980-81 - IPUMS Subset 1981","alternate_title":"PHC pk1981a (IPUMS Harmonized Subset)"},"authoring_entity":[{"name":"Population Census Organization","affiliation":""},{"name":"IPUMS","affiliation":"University of Minnesota"}],"production_statement":{"copyright":"(c) Copyright 1981, Population Census Organization and Minnesota Population Center"},"distribution_statement":{"contact":[{"name":"Population Census Organization","affiliation":"","email":"","uri":""}]},"series_statement":{"series_name":"Population and Housing Census [hh\/popcen] IPUMS International","series_info":"DOI:10.18128\/D020.V7.6"},"version_statement":{"version":"Version 7.6.

The details of the confidentiality protections vary across countries, but in all cases, names and detailed geographic information are suppressed and top-codes are imposed on variables such as income that might identify specific persons. In addition, IPUMS International uses a variety of technical procedures to enhance confidentiality protection. These include the following:\n\n(1) Swapping an undisclosed fraction of records from one administrative district to another to make positive identification of individuals impossible.\n\n(2) Randomizing the placement of households within districts to disguise the order in which individuals were enumerated or the data processed.\n\n(3) Aggregating codes of sensitive characteristics (e.g., grouping together very small ethnic categories)\n\n(4) Top- and bottom-coding continuous variables to prevent identification of extreme cases.\n\nThe safety record for public-use census microdata is apparently perfect.
