  1. Web-Based Data Input Method November 2005 National Statistical Office Republic of Korea

  2. Contents • Outline of the Agricultural Census • Recent Issues • Web-Based Data Input Method

  3. Outline • Objectives - For tracking the changing trends in agriculture - Providing Basic Data necessary for policy-making - Updating the frame used for agricultural sample survey - International Data Exchange on agricultural statistics

  4. Historical Background - Under the recommendation of UN/FAO, the First Census was undertaken in 1960 - 1970(2nd), 1980(3rd), 1990(4th), 1995(5th), 2000(6th) - The 7th Census is going to be undertaken in Feb. 2006

  5. Reference date and Field Survey -Reference date : 1st December 2006 -Reference period : from 1 Dec. 2004 to 30 Nov. 2005 -Field survey : from 14 Feb. to 28 Feb.(15 days) • Coverage -All farm households that are managing agriculture themselves in Korea • Data Collection -Temporarily employed enumerators interview with the respondent and fill out questionnaires

  6. Survey Items - Farm Households Population (1) Name (2) Sex (3) Age (4) Relationships of members to the farm manager, (5) Educational level (6) Marital status (7) Main type of work (8) Months spent on Farming (9) Time spent on non-farming (10) Agriculture career (11) Farming Successor

  7. - Agricultural Land (1) Paddies (2) Upland field (3) Orchards (4) Pasture - Crops (1) Harvested area by type of crops (2) Area of Facilities (3) Harvested area under green houses (4) Harvested area specialized in every city, county

  8. - Livestock (1) Korean Beef Cattle, Milking Cow, Pig, Fowls, Honey Bee, etc. -Agricultural Machinery (1) Possession of electronic-powered agricultural machinery (2) Farming methods of paddy rice

  9. - Value of Sales of Agricultural and Livestock Product (1) Scale of sales (2) Major products of sales (3) Route of sales -Environment-Friendly Farming (1) Whether Execute or not (2) Harvested area and farming methods by crops (3) Sales route

  10. - Status of Information-intensive (1) Whether Possess of PC or not (2) Main use of PC (3) Whether open a homepage related to Agriculture - Environment of Residence (1) Type of residence (2) Heating apparatus (3) Kitchen •Toilet •Water (4) Vehicles -Others Participation of Producers’ Organization

  11. Recent Issues • Unite three Censuses: Agriculture Census, Forestry Census & Fishery Census • Change periodicity(10 years→ 5 years) • Develop new items for the new era • Manage systems of the field work • Develop communication tools - Internet homepage & Free Call Service • Catch farm household lists from various sources

  12. Needs to reduce the data processing time - pursue consistency of the serial data of annual sample surveys in connection with the census 1999 20002001200220032004200520062007 1995c census 1995c 2000c 2000c 2000c census 2005c 2005c • Data processing – web-based input - on line, government use only network because of security reasons

  13. Web-Based Data Input Method • Concept After we connect the Census web site, survey-completed data are input and sent to the KNSO’ DB by personal computer in the field.

  14. Background - We need a new input process paradigm, different from OMR, ICR, for processing large scaled data as census quickly. - Data processing method by OMR needs much time, when we make out questionnaires.

  15. - In Korea, high developed IT basement can construct high speed national administration network and spread personal computer per 1 person to all executive agency. - We can meet user’s demand by offering survey’s result quickly for the ‘timeliness’.

  16. Procedure - Preview (1) Construct web site (2) Develop input program (3) Load of server and network (4) Security module & exclusive network (5) Surplus band width of network (6) Input place (7) Prepare equipment

  17. - Data input (1) Educate how to input data (2) Input and modify questionnaires’ data - Editing (1) First editing (2) Second editing

  18. Results of trial survey [Table 1] Overview of trial survey

  19. - KNSO conducted trial survey two times by web-based data input method. - Problems during the trial survey (1) Input program’s screen design (2) input speed (3) Absence of field managers (4) Various input methods

  20. Application - We execute across the board in Feb. 2006, the web-based data processing method compensating for the errors during the trial survey

  21. (1) We make use of national administration network mainly, and also use VPN for security etc.. (2) X-internet method is developed for input program, which has merits between web and C/S.

  22. (1) Screen component and input method are designed simple for users. (2) At input place, we prepare management staffs focused exclusively on PC and network. - Web-based data processing method can shorten input period, but the number of input person is increased.

  23. [Table 2] Overview of Agricultural Census data input methods

  24. Expectation - Raise ‘timeliness’(reduce the time of release about 2 months than that of 2000 Census) - We can release result in Oct. 2006, for the purpose of shortening data input period as early editing.

  25. - Various sample surveys could be improved by taking early sampling surveys so as to reform them later on. - We expect it to improve data correction and reduce the field work in dealing with the missing questions on the questionnaires.

  26. Current Situation of Agriculture • Structural Weakness and Low Competition in Agricultural Sector • Instability and Insecurity of Farm Households’ Income • People are increasingly reluctant to reside in rural areas mainly because of poor conditions in living environment and welfare facilities.

  27. As a result, usual vitality in former days is disappearing in rural communities. • Exposure to world competition system is inevitable and accelerated as time goes by.
