National Survey on Household Consumption and Expenditure 2000-2001
Income/Expenditure/Household Survey [hh/ies]
Household consumption and expenditure surveys represent a valuable source of information which makes it possible to obtain data on household consumption and expenditure. The data acquired through such operations is becoming increasingly important, in economic and nutritional studies as well as in planning.
The last survey about households' consumption and expenditures, made in 1984/85, provided exceedingly pertinent statistical information. However, considering the different socioeconomic changes in the country since that date, available data no longer reflect the current reality. Hence carrying out a new survey, in order to bring up to date available data and update some socioeconomic indicators.
The diversity of their objects, their comlexity and the fact that they are carried out less frequently made that moroccan surveys on the subject have looked for a compromise that can meet the needs for a survey about budget (or expenditures) as well the needs for a survey about food consumption.
The survey's main aim is to collect information, which provides a detailed description of living standards, as well as an essential data basis to help define and assess the social development national strategy.
Analyses and studies, which we can make from information provided by the survey, are plenty. In this respect, the main objects of this nationally recognized operation are as follows:
- Determining the various commodities' ownership expenses pursuant to ownership modes (purchase, home-consumed production, received grants, …) and according to the main socioeconomic determinants.
- Providing data necessary to update living cost index (ICV) balancing factor and some National Accounts aggregates
- Appraising the quantity of food consumed per capita and per household, according to the nature of food products.
- Analyzing food consumption according to the origin of each product (purchase, home-consumed production, received grants, …) and the principal features, demographic and socioeconomic, of consumer households.
- Knowing the Moroccan households' food behavior.
- Assessing the population's nutritional situation.
The survey shall provide basic data that allow for making analyses and studies about some particular aspects of the population's living conditions, namely those related to:
- Market survey and goods and services demand analysis.
- Sharing consumption expenditures among the various socioeconomic groups.
- The analysis of disparities in view of consumption expenditures.
- The study of poverty pattern at the national and regional level.

The ENCDM 2000/01 sampling plan comes within the framework of the master-sample, put in 1983 and updated in 1994, to meet sampling needs of post-poll tax surveys.
The main features of this drilling plan are summed up as follows:
The 'master-sample' expression refers to a set of geographic zones or « primary units » (UP), within which samples to carry out the various surveys with households are chosen.
To elaborate the master-sample, a set of 2 or 3 adjacent survey districts (DR) has been considered as a primary unit (UP); in other words, a primary unit is then defined as an average-sized geographic area with 300 households, characterized by clear limits that allow for field-localizing it, without any ambiguity.
The 1994 population survey districts allowed thus to set up a survey basis made up of 14 948 stratified primary units (8 533 in the city and 6 415 in the countryside).
Master-sample survey basis units have been stratified. Stratification is so desirable that it enables the various users making survey plans that meet efficiently their surveys' objects by ensuring:
- Optimum sample size;
- A significant cost cut ;
- A substantial improvement of estimators' accuracy.
To free oneself from drawdown contingencies, a first dichotomous stratification, which we introduce generally in survey plans in Morocco, is the distinction between the urban and the rural, insofar as socioeconomic phenomena are not the same in both of them. On the other hand, it should also be noted that survey unit's stratification criteria vary according to the residence environment. Used criteria are:
i) Administrative tranching of the national territory into regions and provinces
ii) Predominant « housing standard » for urban zones. These criteria allowed for distinguishing the following five strata: "luxurious", "modern", "old medina", "new medina" and "underground" (including precarious housing).
Survey plan follows one degree stratified sampling principles with remission unequal probabilities. Primary units of the survey basis within each residence environment have been proportionally divided according to the various strata in each environment.
The scheme allowed therefore for making up a 1 575 primary units (911 in the city and 664 in the countryside) master-sample.
Main features of the ENCDM 2000/01 survey plan :
The sample of the concerned survey has been taken from the master-sample and follows two degrees stratified sampling principles. This kind of survey shows more than one advantage. It reduces the survey cost and allows also for improving coverage, works field supervision and the quantity of collected data. Sample selection work can also be reduced.
However, the main drawback is that this survey relatively reduces the sample's efficiency.
The main characteristics of the ENCDM 2000/01 survey are the following:
i) Survey unit : the l'ENCDM 2000/01 survey plan involved a sample selection in two stages :
- first degree : it is about the above-defined sample primary units. For ENCDM needs, a 1250 primary units sample has been selected among the 1575 of the master-sample, i.e. 710 urban units and 540 rural ones
- second degree : the « household » has constituted the secondary unit of the applied survey. Within the framework of the elaboration of the master-sample, lists of households from the various primary units have been established. At the level of each primary unit, a systematic drawdown allowed for selecting 12 households.
ii) Sample size : considering budgetary constraints and the issues linked with the available human and financial means, the sample size is set at 15 000 households. This size was considered sufficient to have reliable estimates according to the residence environment (urban/rural), different socioeconomic categories of the country and the most important regions and provinces (in terms of population).
In a 15000 households initial sample, 14243 complete forms have been operated, i.e. a 5% non-response rate (7,7% in the city and 1,6% in the countryside).

Collection of data in the field:
For a survey as complex and as delicate as that about households' consumption and expenditures, the success of the operation depends a lot on the organization of field works. Failure of staff to collect data in performing their planning can be detrimental to the good process of the operation and may distort results.
Observation method relies, to a large extent, on the mobilized human and financial means. Sample households are observed in one passage during a one-week survey.
Therefore, each team made up of three surveyors and a supervisor work within a primary unit during 12 days divided up as follows:
- The first day is intended for the contact with the household to be surveyed , explaining objects and observing demographic characteristics and dwelling conditions of the surveyed household.
- From the 2nd to the 8th day: forms are filled
- 9th, 10th and 11th days are devoted to the surveyor in charge of the collection to encode forms.
- The 12th day is intended for traveling among primary units to be surveyed.
The surveyor's work planning includes a fixed part, which is to note daily all household members' purchases and a variable part for which he/she is induced to study all the other themes related to the various aspects tackled by the survey.
For households who accept to collaborate, « aide-memoirs » are put at their disposal so that they report daily their current purchases during the “week survey”. The surveyor daily observes, during 8 days, four sample-households.
Data collection in the field:
The survey was carried out by the households' survey division at the Statistics Department with, however, a decentralization of data collection and question encoding requiring return to nomenclatures. Thus, each one of the regional departments was in charge of making the survey in the sample zones within its territorial field.
Field data collection works started on November 1st, 2000 and ended on October 31st, 2001.
The human (including reserve) and financial means mobilized to carry out this operation are made up of : 16 supervisors, 43 controllers, 128 surveyors, 43 drivers and 43 vehicles.
Five questionnaires or forms had been used to collect the survey data.
1) Form A: Demographic and Social Characteristics
2) Form B: Consumption and Current Food and Non-food Costs
3) Form C: Non-food Costs
4) Form 4: Section 4 of Form "A"
5) Community Questionnaire/ Form
