Specific Instructions by Items
To ask the questions correctly, follow the instructions for each item of CPH Form 2. The rationale and/or importance of each item are explained.
D1-Floor Area of the Housing Unit
Item D1--Floor area of the housing unit shall be asked from a responsible member of any household in the housing unit.
Density of occupancy, expressed as the number of persons per unit of floor area, can be used as a measure of housing adequacy. The so-called "crowding index" is based on this measure. Data on floor area can provide information on the current status of the density of occupancy of existing housing units in the country. This item can also be used by planners and policymakers in the adoption of housing standards that will provide adequate housing space to a level consistent with the maintenance of health and general living conditions of the occupants.
Write "X" in the box corresponding to the estimated floor area of the housing unit. The codes and the categories for floor area are presented below:
[] 01 Less than 5 square meters/ less than 54 square feet
[] 02 5-9 square meters/ 54-107 square feet
[] 03 10-19 square meters/ 108-209 square feet
[] 04 20-29 square meters/ 210-317 square feet
[] 05 30-49 square meters/ 318-532 square feet
[] 06 50-69 square meters/ 533-748 square feet
[] 07 70-89 square meters/ 749-963 square feet

Floor area refers to the area or space enclosed by the exterior walls of the housing unit. In case of housing units with several floors or storeys, get the area of each floor/storey in square meters or square feet and add them together to get the total floor area of the entire housing unit.
There are many ways in approximating the total floor area. You may use any method convenient to you such as, use a meter stick, visual approximation (using your eyes only), or pace factor (see Appendix 10, page 264). In case the respondent does not know the floor area of the housing unit, you can approximate the floor area using any of the aforementioned methods. Familiarize yourself with the length of a meter so that you can do visual approximation.
An example of getting the estimate of floor area is shown in Illustration 7.5 on the next page. In this illustration, it is assumed that the width and length of the floor spaces are already determined using one of the methods discussed above.
[pg. 142]
To get the estimated floor area (EFA) of the ground floor, use the formula:
ground flood = 10 meters x 7 meters = 70 sq. m.
Use the same formula for the second floor:
EFA second floor = 10 meters x 9 meters = 90 sq. m
.
To get the total estimated floor area of the housing unit, which will be the answer to the inquiry "What is the estimated floor area of this housing unit?" The formula is :
EFA ground floor + EFA second floor = 70 + 90 = 160 sq.m.
For this example, write "X" in the box opposite the range of values that includes the given answer, that is, 150-199 sq. m. (code "10"). [Image omitted.]
