MICS Data Processing Workshop The Data Dictionary and Forms

Questionnaire Types There are three types of questionnaire – Household – Women – Children Each type has core, additional and optional modules

Identification Variables

Module Naming Conventions Each module corresponds to a record A records name is MODXX – where XX is the modules code For example, the child mortality module is named MODCM Two exceptions: – Household listing stored in MODHL and MODTO – Orphaned children stored in MODOV and MODOR

Repeating Modules There are 6 repeating modules – Household listing – Education – Orphaned and vulnerable children – Child labour – Disability – Maternal mortality Stored as repeating records

Variable Naming Conventions Variables are named for – Their module – Their number Question 5 in the HL module is named – HL5 Next slide describes the only exceptions to this rule

Source and Response Variables A few questions have two parts – 1 st part is the source of the response – 2 nd part is the response Questions stored in two variables – Source has letter A as a postfix Question 2 of the AN module – AN2A – lying or standing up – AN2 – height

Subitems CSPRO allows one to define subitems A subitem is a portion of a variable (or item) Both the item and the subitem can be referred to in an application We make extensive use of subitems The situations in which we use them are described in the next four slides

Multiple Response Questions There are many multiple response questions – Interviewer can circle more than one code – e.g. question 2 of MN module These variables are stored as alphanumeric variables whose width is the number of responses For each response there is a subitem whose name is the variables name plus the responses code For example, response A to MN2 is stored in subitem MN2A

Date Variables Date variables with several parts (e.g., month and year) are stored in a single variable The single variable has a subitem for each part of the date The subitems are named using the module, question number and D, M or Y – e.g., the day of household interview is stored in subitem HH5D

Unit and Number Variables A few questions have two parts where the – 1 st part is the form of the response (i.e., the units) – 2 nd part is the response (i.e., the number) These variables are stored in a single variable with subitems – subitems have U and N prefixes in their names Example: question 13 of the MN module – MN13U - hours or days – MN13N - number of hours or days

Level and Grade Variables In the ED module, 3 questions record level and grade Stored in single variable with subitems – Level subitem has A prefix – Grade subitem has B prefix Example: question 3 of ED module – ED3A - highest level – ED3B - highest grade at that level

Coding Conventions

Dictionary and Form Modifications Work in CSPRO on Form File! Add/remove modules and variables to dict. Modify variable characteristics if necessary – e.g., lengths, ranges and variable and value labels Update forms to reflect dictionary changes Reorder forms flow (if variables added)
