Abstract
The non-agricultural sectors of the economy account for about 50 percent of GNP and about 40 percent of employment and are growing very rapidly. These sectors (especially the small scale sectors) are precisely the ones with the weakest data available. Improving this situation requires the 'conduct of a comprehensive sample survey designed to collect the appropriate information. However, without a -knowledge of the number and location of establishments classified by industry, no useful and reliable surveys can be conducted. This can only be obtained through a census of non-agricultural economic activities.
There has never been a census of economic activities describing the economic structure and industrial composition of theBangladesh economy. Although some data are being regularly compiled (notably the census of manufacturing industries), most of the previous surveys have been adhocefforts conducted by diverse organizations covering only a very selected universe. As such, the results have been very difficult to compare and have presented very different pictures of the actual situation. The unorganized sector of the economy in particular, suffers from an almost complete lack of reliable data and that which are available conflict in many details. It should be noted that the non-agricultural economic sector must become stronger in the future if it is to absorb the increasingly larger number of landless persons. Accurate information is a necessity for careful short and long term planning efforts in this critidal sector.
The specific objectives of the proposed Economic Census were:
- To determine the structure of the non-agricultural economic sector and measure the relative contribution each makes to the regional and national economies.
- To furnish benchmark figures for revising and up-dating the national income accounts and other economic series covering the non-agricultural economy of Bangladesh.
- To provide a frame for planning and designing future, more frequent in-depth surveys of non-agricultural economic activities.
- To collect basic data on economic activities, persons engaged (working proprietors and partners, full-time and part-time employees, family workers, and by sex), the year business was established, type of machinery used, and type of ownership.
- To determine non-agricultural economic activities done by households in the nonformal sector.
- To provide small area statistics for users both at national and local levels and support the government in its policy of decentralization of planning and functions.
- To derive a base for the formulation and implementation of a comprehensive and integrated plan for the development of the non-agricultural sector.
The industries to be covered included all non-agricultural establishment based economic activities such as mining quarrying, manufacturing (including cottage industry), production of electricity, gas and water, construction, trade, services, transport, storage, communication, finance, insurance and real estate, in short, all non-agricultural activities carried out in the formal and non-formal sectors. Data to be collected included the name and address, a description of the activity conducted, major products sold or serviced, method of selling, type of ownership, number of persons engaged (working proprietors, partners, full and part-time workers, unpaid family workers) classified by sex, type of machinery used, year of establishment and type of ownership.

Coverage

Universe
In the case of Economic Census, the proprietors and managers of business may sometimes be reluctant to disclose correct or accurate detailed information about their economic activities and other related information. Some of them may be. afraid that the Government may either enhance existing taxes or impose new taxes on their economic activities, or take some other action that may adversely affect their economic situation. It is felt that the census -enumerators would naturally face problems regarding their legal authority of collecting such informations. It is therefore, necessary to provide a legal basis to the 1986 Economic Census.
To conduct a nation-wide Economic Census by the staff of the Bangladesh Bureau of Statistics alone was impossible. A large number of persons were required to work as census enumerators and supervisors. These officials were recruited from amongst the members of the public or borrowed from other organizations having field staff. With a view to facilitating availability of requisite number of officials either from amongst the members of the public or other organizations to the Bangladesh Bureau of Statistics during the census field operation it was considered necessary that the members of the public or other organizations were made legally bound to render necessary assistance towards taking of the census; and it any body refused or neglected to perform any census duty imposed upon him or refused to obey any order issued to him under the legal authority vested bylaw in the Bangladesh Bureau of Statistics, such offence should have been made punishable under the law. In view of the circumstances stated in the previous paragraphs, the Government of Bangladesh adopted "The PresidentiaJ Order No. 70'of 1972" (Population Census Act) for the purpose of conducting the 1981 Population Census in Bangladesh.
The Economic Census of 1986 was conducted to collect statistics regarding economic activities and disabled persons including the head count of population as additional information. For field enumeration of this census, enumerators had to approach households, business/industrial establishments, institutions, etc. As such for conducting this census the aforesaid "Census Act" (Appendix-i) and the "Industrial Statistics Act, 1942" (Appendix-2) were adopted as legal base. Both of these acts authorised the census enumerators to gain access to the households and premices of business/industrial establishments and other institutions and organizations for marking or asking questions for the purpose of conducting the census. Both acts made it obligatory on the part of the respondents to answer questions put to them by the census enumerators. Any person who knowingly made any false return, or intentionally gave a false answer or refused to answer to the best of his knowledge was made punishable by these acts. Similarly these acts imposed certain responsibilities on the census organization and ensured strict secrecy on the information collected during the census operation. The collected information would not be disclosed publicly and none could have a right to inspect any book, register, or record made by a census officer in the discharge of his census duties and no records of census would be admissible in .any civil or, criminal proceedings other than a prosecution under the census act.

Sampling

Sampling Procedure
Following the census, the BBS conducted a series of large scale sample surveys covering the nonagricultural economic sector.
They were:
- Integrated Economic Survey in the formal sector.
- Survey of Household and Cottage Industry in the non-formal sector.
The census results were used as the sample frame. Each subject was explored in greater depth than was possible In a full scale census. For example, to get a reasonably accurate response on sensitive items such as value of inputs and outputs from businessmen requires a probing set of questions which was not possible in a census enumeration. The continuing series of economic surveys would be based on the results of the economic' census' both as a sample frame and as a benchmark for accurate estimation procedures.
Deviations from the Sample Design
In view of the emphasis of the Economic Census on non-agricultural economic establishments and the disproportionate concentration of such establishments in urban areas, oversampling of urban areas for the PEC was deemed essential. The desire for separate PEC coverage estimates for the large and small cities dictated a further concern for over sampling in urban areas. A third factor bearing on the issue of sample allocation was that census coverage would be lower in urban areas than in rural areas again indicating an additional measure of oversampling in urban areas. At the outset, it was decided that a total sample size of 250 EAs would provide reliable estimates and would be within the resource capabilities of the BBS.
On the basis of pre-census EA lists, the whole country was divided into three domains (a) large cities, (b) small cities, and (c) rural areas including other urban areas. Then on the basis of the activity of the units each domain was divided into two strata : (a) commercial and (b) residential.
a. Selection ofcommerclal EAs
All mauzas with hats/bazars were classified as "Commercial mauzas". In a first stage selection,these "Commercial mauzas" were selected PPS according to the number of EAs in each mauza. The exact EAs were selected in a second stage, during the PEC-A operation. The "Commercial" mauzas were inspected to determine exactly which EAs contained hats/bazars. Those with hats/bazars were classified as "CommercialEAs"; those without hats/bazars were classified as "Residential EAs". In the second stage, "CommerciaEAs"weré selected randomly within the selected "Cormercial mauza".
b. Selection of Residential EAs
All "Residential EAs" were selected in a two-stage sample. The "Residential mauzas" (those mauzas without hats/bazars) and the "Commercial mauzas" were groupedtogether and mauzas were selected PPS according to the number of EAs in each mauzas. Forty-one of these selected mauzas were "Residential mauzas" and nineteen were "Commercial mauzas". EAs within the "Residential mauzas" were selected by a systematic procedure while the EAs within "Commercial mauzas" were selected randomly during the PEC-A operation as stated in Para-a above.

The Annual Economic Survey (AES) sample design is based on two in independent frames a list frame based on the industrial directory of large establishments, and an area frame to cover the smaller establishments, the household economic activities and the large establishments missing from the list frame. The sample design for the area frame provided for 12 monthly national subsamples of approximately 125 EA's each. For the purposes of the area frame sample design, 107 distinct BSIC groups were defined for permanent establishments. Some of these groups consist of establishments at the individual 4-digit BSIC level, while 4-digit BSIC groups with few establishments were combined. The data for the first 3 monthly area subsamples were used to calculate the approximate variances for total TPE for each of the 107 BSIC groups. In order to determine the precision of the combined area and list frame survey estimates, the list frame variances based on the final sampling strategy were calculated for the same 107 groups. These results are presented in annex 3, which includes the C.V.'s for the combined estimates.
The purpose of this report is to define the sample design for the list frame of large establishments. First the issues related to the integration of the Census of manufacturing Industries (CMI) and AES list frame for the manufacturing sector is described followed by considerations for stratification and optimum, sample allocation. Detailed sampling specifications are included to be used in the selection of the sample establishments by Microcomputer.

Data Processing

Cleaning Operations
Input preparation planning;
The data processing was the most important part of a census operation. it consisted of three distinct operations. A manual editing and coding phase prepared the questionnaires for the Optical Mark Reading (OMR) phase accomplished by high speed DMA machines. The OMA data tape output was then read into the BBS mainframe computer where the data were further edited for completeness and accuracy, corrected where necessary and then tabulated for review and publication.
Manual editing and coding;
The first phase of data processing involved - (i) sequential arrangement of 1,96,720 filled in census books according to geo-code, (ii) verification of geo-code and (iii) manual editing, coding and coverage control. Immediately after receipt of the filled in census schedules from the field, these were arranged by District, Upazila, Zone, Union/Ward according to the geo-codes assigned to them. Manual,editing and coding were taken up just after the filled-in census books were sequentially arranged. Each EA book was processed in the following manner
Coding of economic activities;
A "Code" is numeric symbol by which information can be classified or organised. The Bangladesh Standard Industrial Classification (BSIC)-1 986 had been developed in conformity with lntemational 0 Standard Industrial Classification to assign unique code to economic activities. A team of. trained càders assigned a 4-digit BSIC code to each questionnaire for each unit with economic activity. Each: coder was supplied with coding manuals in both English and Bengali which, showed the entire coding* structure with detailed descriptions of. each classification. A supplemental alphabetic index was prepared in both languages to assist coders in quickly determining the correct codes. The entire coding operation was subjected'to a rigorous uaiity control operation (QC). Every coders work was 100% verfified until the coder demonstated that he/she was "qualified"; following which each coderswork'was verified at a 10% - level. The ve'rdicatio'n'wab done independently; the verification coding was done on a separate coding sheet by coder A, the actUal coding in the EA book was done by coder B, and comparision coder, coder C, compared the two results and prepared the necessary QC documents. These documents were used to monitor control of the coders production and error rates and to measure the quality of the coding operation. With the coding work completed following the abovö procedure, the error rate was less than 1 percent.
