In the 2010 Census, more than 190 thousand enumerators visited 67.6 million housing units in the 5,565 Brazilian municipalities. This website brings information about all the steps of the 2010 Census, with special highlight to the survey results.

  • Can I answer the Census through the Internet?
    Yes, you can. Answering through the Internet will be possible in the 5,565 Brazilian municipalities.
  • How do I answer the Census through the Internet? The option to fill the questionnaire through the Internet can be requested to the enumerator during his/her visit to your housing unit. In this case, the enumerator will give you a sealed letter containing the instructions to access the questionnaire in a specific website. It also includes an exclusive access code and the security passwords.
  • Is it safe to fill the questionnaire through the Internet?
    The IBGE provide security features, like authentication, encryption and authenticity validation of the website. The authentication in the online questionnaire is made through a unique access code and a table of different passwords. These data will be available in a sealed letter along with the orientations to fill it out, which will be given by the enumerator at the dweller´s housing unit. The online questionnaire also uses a security certificate recognized by Verisign. In addition, the https security protocol assures the encryption of the data throughout the network, thus assuring the protection of the user data.
  • I am answering the questionnaire through the Internet and I have some doubts about some concepts and about some questions. Whom am I supposed to contact?
    The online questionnaire has a number of help tools. They provide links explaining the concepts and icons to help the filling. Should you have any doubt about the concepts, you need to mouse over the word, which has a different color, to read the explanation. Some questions have a question mark and you should mouse over it to read the explanation. If you still have doubts, you should contact the IBGE on 0800 721 8181.
  • Will the Census 2010 questionnaire be available on the IBGE home page?
    The Census 2010 questionnaire is available for inquiry only. To answer it, you should access it on a specific link using the access code and password provided in the letter given by the enumerator.
  • After receiving the sealed letter, how much time do I have to fill the questionnaire through the Internet?
    The questionnaire can be filled on the Internet up to five days after you receive the letter with the instructions.
  • Should I answer the questionnaire all at once?
    It is up to you to answer the questionnaire all at once or in parts, since the system saves the answers automatically. Nevertheless, the questionnaire has a limited access: you can access it up to 40 times, since the letter includes 40 security passwords. Each time you access the questionnaire to answer the questions, the system will request a password included in the password table provided in the letter.
  • I lost the letter with the access code to the questionnaire given by the enumerator. How should I proceed?
    Contact the IBGE through the telephone 0800-7218181, from Sunday to Sunday, from 8am to 10pm, to inform the loss of the letter with the access code. If the access code was lost before beginning to fill the questionnaire, the enumerator will return to your housing unit with a letter containing a new access code, which will overwrite the old one. If the access code was lost after beginning to fill the questionnaire, the enumerator will return to your housing unit with a letter containing the same access code for you to continue to fill the questionnaire from where you stopped, since the answers provided before the loss of the access code are saved by the system.
  • What happens if I do not answer the questionnaire on the Internet within the deadline?
    If the questionnaire is not filled out in five days, the IBGE will contact you through an automatic telephone call. If you do not answer the questionnaire within 48 hours after this call, an attendant of the IBGE´s Call Center will call you to remind you. Should you not answer the questionnaire, you will be visited by the enumerator once again to carry out the interview face to face.
  • What guarantee do I have for answering the 2010 Census through the Internet?
    At the end of the filling, the system will provide a receipt number confirming that the questionnaire was filled out successfully.
