UK Data Archive Study Number 4397. International Passenger Survey, 2000. The Coder's Task A Coders should check for: · completeness · legibility · consistency · accuracy and correct the coding if necessary in the following sections: UK county/specified foreign state Airport started/ends journey Date visit began Class of travel Number of people Type of flight Whether package or not Origin / destination Package cost and insurance Shipping company Expenditure section Sea port or origin/destination Alcohol / tobacco Vehicle on board Towns section Sea fare Migration Qs 18 - 22 Shift details Airline and airport Type/date of interview End/transfer The coder’s task, page 1 B Coders should check for legibility and completeness but not accuracy in the following sections. Any missing codes are to be inserted and any illegible codes are to be corrected. Nationality Fare not applicable (Sea) Residence Classification Country visited Coding complete Reason for visit Interviewer's number Length of stay Interview time The work of new interviewers and others as specified by the Research Officer as well as all migrant records (i.e. those with a length of stay of 12 months or more) should be checked for consistency and accuracy in the sections listed in B above. C Coders should insert the correct codes in the following sections which are not routinely coded by interviewers. Migration/long stay visitors Qs 17/17a, 24/24a, 28 Air fare Sea fare The coder’s task, page 2 Documents used by coders to code or check questionnaires Questionnaires Interviewers' instructions Coders' instructions Coding frames Quarterly List of air and sea and tunnel shifts Fly Drive instructions Mayfly - particular to an air shift JP Airline Fleets JP Guide to Airlines OAG World Airways Guide (Monthly) OAG Shipping Guide (Quarterly) Calendar CODOT (Classification and Description of Occupational Titles) 1972, Department of Employment (HMSO) Census Place Names 1981 - for Coding of district for migrants and town/county coding Index of Scottish place names AA Big Road Atlas - Britain World Map Index of hotels London A-Z Compiled monthly by SSD: Currency conversion table Diesel prices Eurostar fares (update when new guides produced by Eurostar) Compiled quarterly by SSD: Air fares by class for each month (from OAG World Airways Guide) IT air fares for each month ( “” “” “” “” “”) Sea fares and shuttle fares (compiled from ferry operators' and Eurotunnel brochures).

Updated as required by SSD: List of interviewer authority numbers Contact list (addresses and phone numbers) Documents used, page 3 General points Items which will be entered on computer are marked by a bold outline on the questionnaire. The CADI program expects the full number of digits to be entered except for fare/expenditure amounts and number of nights in towns which need not have leading zeros inserted. (These are inserted by data processors). If a code has to be changed, cross through the old one and write the new one above or below; do not erase. Corrections will sometimes have to be outside the coding column. All coders' entries should be in red. The final code input on the CADI or the database must be clearly recorded as such on the questionnaire. Always distinguish between: blanks - where a question does not apply 9s - where a question should have been answered but the answer is not known. 0s - where a quantity is nil. All codes are numeric not alphabetical with the exception of the district codes at Q17, Q17a flight number and the indicator fields attached to quantity variables. General points, page 4 Types of questionnaire Questionnaires fall into several categories according to 'flow' and amount of information given. Flow There are eight flow codes; they are derived from questionnaire type and residence. It is not necessary to enter the code on the questionnaires. Code Questionnaire Residence (Qs 2-7) 1 Air departures Foreign Pink 2 Air departures UK " 3 Air arrivals Foreign Blue 4 Air arrivals UK " 5 Sea departures Foreign Green 6 Sea departures UK " 7 Sea arrivals Foreign Yellow 8 Sea arrivals UK " 5 Eurostar departures Foreign Purple 6 Eurostar departures UK “ 7 Eurostar arrivals Foreign Grey 8 Eurostar arrivals UK “ Flows 1, 4, 5, 8 are 'main' flows because they refer to people ending their visits and include all expenditure data. Identification Quarter- generated by computer from the date of interview. Serial number Each record has two serial numbers. The first is an SSD serial number used for field work purposes. It is a 6 digit number unique within quarter: the first three digits are the shift number (unique within quarter for each shift) and the second three digits are the interview number within shift. The second serial number is a 5-digit number used by the IPS Branch and is again unique within quarter. Records are numbered consecutively from 1 within quarter in the order they appear on the data tape (i.e. shift number order within month). Month 1 records begin at serial number 1, month 2 at 30001 and month 3 at 60001. Shifts are numbered chronologically within air shifts, sea shifts and channel tunnel shifts, with air shifts having the lowest numbers followed by sea shifts followed by channel tunnel shifts. The IPS Branch serial number is attached to the final data file and is not on the questionnaire or in the CADI. Note: On most air questionnaires you will find numbers written by the interviewers at the top left corner of page 1 e.g. 24/600 Types of questionnaire, page 5 This means that the respondent was the 600th passenger on the counting clicker (and the 24th selection on that shift). These numbers are not entered on computer and are not serial numbers. However, they can be useful when checking flight information because in conjunction with the traffic statistics they give an indication of the hour during which the interview took place. Minimum questionnaires There must be codes entered at: Question Quarter - Flow - Serial number - Nationality 1 Residence 2-5 Sex 86 Age 87 Response 99 Date of shift 99 Interviewer - Main Air Sampled port (+ shift) 96-98 Sea and tunnel Shipping line 71, Port 72 Partial Questionnaires As for minimum questionnaires plus at least: Question Reason for visit 9or35 Date visit began 29f (arr) or 29f-34 (deps) (if applicable) Country visited 34 (arr) (if applicable) If any of these is applicable but missing the interview becomes a minimum, even if other questions are answered. A partial may contain more information than the fields given above. Types of questionnaire, page 6 Referrals by coders Interviewer Queries For minor queries telephone the interviewer. For more complex queries, or queries requiring the interviewer to see the questionnaire, make two copies of the questionnaire pages relevant to the interviewer. If you cannot decipher which interviewer did the interview flag it for the Field Officer to find out. Use the query sheets. Be specific as to what you want the interviewer to answer. e.g. Town, illegible, please decipher Is '£300' to be deducted from £1000; calculation not clear Please explain why you coded country 'x'. Do not refer unanswered questions or incomplete answers to the interviewer if the interview was partial and that question not reached or if the interviewer has clearly endeavoured to probe out the answer but been unsuccessful. The cases to refer to interviewers are given on next page. Research Officer Queries Be specific on the query. The Research Officer may sometimes decide to refer it on to the interviewer. Some referrals are requested in cases where the Research Officer or interviewer cannot fill in the missing detail but there is a need to be aware of the inadequacies in case they can be reduced by training. In such cases write 'For Information' at the top and note the inadequacy. Site manager referrals Give copies of referrals to interviewers or other questionnaires where training is required to the relevant Site manager on a monthly basis. Referrals by coders, page 7 What to refer to whom To refer to interviewers Examples are: General · Illegible words · Confused recording of calculations etc. Q2-7 Residence · Inconsistency between residence coded (UK/foreign) and the part of questionnaire completed. · Ambiguous residence; it is not clear why the interviewer coded a country or s/he has not indicated which of several countries was residence. · Respondents whose reason for visit is work or study and there is a possibility that the respondent has begun residence in the country of work or study and so been misallocated to UK or foreign residence. · Babies under 12 months old: no evidence of check whether it is first time of entering/leaving the UK and whether baby should be a migrant. Q8 / 34 Country visited · Vague area, no note explaining why vague. Q9-15, Q35-43 Reason for visit · Personal/private - no evidence that interviewer probed it; ask if s/he can give any more detail. · Notes and code inconsistent - say which code you would allocate on the basis of the notes and query which code applied. Q17-28 Migration · Migration questions answered but length of stay not answered or coded as 1 · No evidence that month of last migration checked if it was 'last year'. · Improbable combination of answers for year of last migration, age. · Number of people migrating not given. · Notes about money taken out/brought in/transferred unclear or not asked. Q29-33 Date visit began · Not clear what the latest date of arrival is - poor recording. Q44-45 Number of people · Indication that the respondent was travelling with others at some point but the number pertinent for expenditure is not given or unclear.
