Household Possession of Mosquito Nets 

 

Percentage of households with at least one mosquito net, percentage of households with at least one insecticide-treated net (ITN), average number of mosquito nets, average number of ITNs, percentage of households with at least one mosquito net for every two persons who stayed in the household last night, and percentage of households with at least one ITN for every two persons who stayed in the household last night

 

Definition

 

1)      Percentage of households with at least one mosquito net.

2)      Percentage of households with at least one insecticide-treated net (ITN).

3)      Average number of mosquito nets per household.

4)      Average number of insecticide-treated nets (ITNs) per household.

5)      Percentage of households with at least one mosquito net for every 2 persons who stayed in the household last night.

6)      Percentage of households with at least one insecticide-treated net (ITN) for every 2 persons who stayed in the household last night.

 

Coverage:           

Population base: Surveyed households (HR file)

Time period: Current status at time of survey

 

Numerators:

1)      Number of households surveyed with at least one mosquito net (treated or untreated) (hv227 = 1)

2)      Number of households surveyed with at least one ITN (any of hml10_1 – hml10_7 = 1)

3)      Sum of the number of mosquito nets (hml1)

4)      Sum of the number of ITNs (sum of nets with hml10_1 – hm10_7 = 1)

5)      Number of households surveyed with at least one mosquito net (treated or untreated) for every 2 persons who stayed in the household the night prior to the survey, in households with at least one de facto person who stayed in the household the night prior to the survey (hv013 > 0 & hml1/hv013 >= 0.5)

6)      Number of households surveyed with at least one ITN for every 2 persons who stayed in the household the night prior to the survey, in households with at least one de facto person who stayed in the household the night prior to the survey (hv013 > 0 & (sum of hml10_1 – hml10_7 = 1)/hv013 >= 0.5)

 

Denominator:

a)       Numerators 1-4: Number of surveyed households

b)      Numerators 5-6: Number of households with at least one de facto person who stayed in the household the night prior to the survey (hv013 > 0)

 

Variables: HR file.

hv013

Number of de facto members

hv227

Has mosquito bed net for sleeping

hml1

Number of mosquito bed nets

hml10_1 – _7

Insecticide-Treated Net (ITN)

hv005

Household sample weight

 

Calculation

 

For percentages, numerator divided by denominator, multiplied by 100. For average, numerator divided by denominator.

 

Handling of Missing Values

 

Households with missing information on ownership of nets are considered not to own nets. For the average number of mosquito nets, missing information on the total number of nets is counted as one net if the household reports at least one net (hv227 = 1). Nets with missing information on type are considered not to be ITNs.

 

Notes and Considerations

 

ITN ownership indicators are highly influenced by the timing since the last ITN mass distribution campaign in a country.  Some surveys collect information on more than 7 nets. Please check variable hml10_#.

 

Changes over Time

 

An insecticide-treated net (ITN) is a factory-treated net that does not require any further treatment. Prior to 2018, this was known as a long-lasting insecticidal net (LLIN).
