Planification of Census 1991

  • Research Method

For the execution of the 1991 Census, Aruba was divided into 45 enumeration areas. Each of these areas was subdivided into several enumeration blocks. An enumeration block comprised a territory containing 25 to 30 addresses. Each enumeration block had to be sufficiently large to be covered by one enumerator during the Census week. For the division of Aruba into about 650 enumeration blocks, a team from the Central Bureau of Statistics did extensive fieldwork in all parts of the country. Based on this fieldwork, detailed maps were drawn. The different enumeration areas and enumeration blocks were outlined on these maps.

A team of enumerators was formed for each enumeration area. Each team was supervised by a head enumerator. The head enumerator was responsible for all the counting activities within the enumeration area. One or two assistants were added to each head enumerator. The main task of these assistants was to inspect the data on the forms for possible errors. A total of 764 head enumerators, assistant head enumerators, and enumerators participated in the 1991 Population and Housing Census. The majority of the Census field staff were teachers and public servants. All teachers and civil servants who participated in the enumeration were exempted from duty, with retention of income.


  • Research period

The enumeration activities of the 1991 Population and Housing Census took place during the week of 6 through 13 October. During the Census week, data was gathered with reference to the situation at the Census moment of October 6th, 1991, 0.00 hrs. The coding of the Census forms was finished by mid-April 1992. All forms were manually inspected for coding errors. Data entry of the Population Census was done by keying the information on 5 micro computers by 9 operators during two work shifts. All data was double-keyed for verification. The process of data entry and verification was finished during the first week of May 1992. Data was extensively edited to detect structure errors, inconsistencies, and non-valid values. The selected tables of the Census were published in October 1992, a year after the census fieldwork.

Execution of Census 1991

  • Employees of Census 1991

All enumerators who participated during Census 1991 followed a 4 hours training. In the training, the enumerators got an ample explanation regarding the contents of the questionnaires and the procedures to be followed during the Census week.  A total of 15 training sessions were given in the period of September 16 to 27, 1991. There were separate training sessions for head enumerators and assistants.


  • Publicity campaign

In order to guarantee the success of the Census, a publicity campaign is of paramount importance. For the Census 1991, different methods were used in order to get the attention of the Aruban population. There was a jingle on the radio, a tv commercial and different advertisements and articles published in the local newspaper. Banners, posters and folders were also printed in order to inform each and everyone on the island about the contents and the importance of Census.
