2. De jure. Usual residents within nation’s boundaries and their dwellings. Face-to-face interview using two types of census forms. One only form was applied in each dwelling. The head of the household, either woman or man, his or her partner, or a resident age 15 years and over. June 12, 2010. From May 31 to June 25, 2010. Type of Census Observation units Collection method Proper respondent Reference moment Census-taking period

3. Building list. Short form: 29 questions; long-form: 75 questions. Urban environment form applied to localities of more than 5 000 inhabitants Locality form applied to localities of less than 5 000 inhabitants. Review of dwellings pointed out as outstanding, uninhabited, or seasonally vacant. To provide coverage indicators and determine sub-coverage. Register of all buildings Dwellings, households, and persons Urban environment characteristics Localities characteristics VerificationPost-enumeration

4. To define the responsibility areas according to ground characteristics, and the balance between workloads and control areas by a fully automated system. To update the whole country mapping in 2008, 2009, and even during the information collection by satellite images and field canvasses. To enable specialized instructors so as to train directly on the long-form and train in cascade on the short form, highlighting practice. To assure the coverage, improve nonresponse and to follow-up the progress of the enumeration operations. Improve data quality. Timeliness of data. Final results were presented in March 2011.

6. The census sample aim at providing reliable and accurate information that can be measurable to be used on rates, averages, and proportions. The design of the census sample is cluster-stratified and was made in a single selection phase. The Sampling Primary Units (UPM) are full geographic areas, either blocks or localities. Because of sampling control and operative reasons, for the cluster of localities with less than 250 inhabited dwellings, the sampling primary units were full localities either with blocks or without them. The updated cartographic catalogue by April, 2010 was taken as the basis for the development of the sampling framework with the statistical information within the System for Development of Responsibility Areas (SICAR).

7. Demarcation: Number of displayed figures Layers: Managament of geographic information layers Group: It displays information of conformation made Unit: Statistical information of a selected geographic object Automated planning model proposing a delimitation of responsibility areas an allowing for their adjustment.

8. Aims: To view areas (localities, AGEBs, Blocks) presenting risks by single operative control stretch. Represent risk “intensity” by a color range. To register the solution strategy given to risks in every area. Easiness to assign new risks to areas according to vulnerabilities observed in field. To transfer risks map to ascending and descending control stretches. To represent new areas registered in Census Mapping Module. Generating operative risks map to support making differently census-taking strategies.

10. To integrate operative staff according to profiles and functions of each position within census structure. To implement a tool allowing to follow-up the processes of recruitment, selection, training, hiring, and administrative changes of staff required to the development of activities. 2

11. Providing a tool to send backups generated with SICAR to headquarters for validation, and the mean to capture information about offices directory and material delivery points to operative staff appointed to make forming of operations responsibility areas. Validation process for operative staff by headquarters.

12. To assure operative staff having materials, supplies, places and necessary infrastructure to make field operations in due time and form.

13. To set and operate a follow-up system accounting for coverage progress, sub-coverage issues, over-coverage issues, and information flow control at workload level.

14. To identify and, if necessary, to correct the occupancy status of dwellings (uninhabited or seasonally vacant) during the population and housing census-taking to reach the best coverage in the Mexican census history. To verify a sample of uninhabited or seasonally vacant dwellings in the urban areas. To verify the buildings intended for uses others than habitation in order to confirm the absence of usual residents. To verify the dwellings having outstanding classification aim at carrying out the interview and bringing nonresponse down. Full blocks were verified. The blocks with the highest number of uninhabited or seasonally vacant dwellings were selected. Approximately 40% of uninhabited and seasonally vacant dwellings were verified.

15. Of the budget: 372.42 million dollars, equivalent to 3.80 dollars per person, 76% was used for training and employing 190 thousand persons: 140 thousand were enumerators or supervisors, 8,200 instructors, and over 7,000 typists. 72% of the staff were women 79% was younger than 34 years old 1% was older than 55 years old 40% of the staff had al least one high school or higher education course accredited 18% had a bachelor’s o master’s degree 6% spoke an indigenous language

16. 1,306 Offices for municipal coordination 909 Capture centers 16,700 Installed computer equipments 2,600 Voice and data services (telephone and Internet) 7 Field control systems 3 Capture systems Reception and storage (working in a local way) Capture (working in a local way) For send the information to headquarters

17. Additionally, different segments of society provided countless support.

18. Coverage on this areas was 99.96%. Access was unable in 1,057 blocks or localities, representing 0.04% of the total areas with a little more than 17,000 dwellings. 98.4% of the country’s dwellings were successfully enumerated, and no response was obtained from 1.6% of dwellings. 192,245 localities. The total population was 112.3 million. Identified and typed 35.6 million homes.
