Statistical concepts and definitions
Terms and concepts for ICT Access and Usage for Households and Individuals:
- Information and Communication Technology (ICT):
Information and Communication Technology (ICT) consists of hardware, software, networks, and media for collecting, storing, processing, transmitting, and displaying information (audio, data, text, images), as well as related services.
- Access and usage of Information and Communication Technology (ICT):
It is important to distinguish between what we mean by access to information and communication technology (ICT) and the use of this technology. ICT access refers to the availability of this technology to a household. The use of Information and Communication Technology (ICT) refers to the use of ICT by one or more household members, whether at home or elsewhere.
- Internet:
The Internet is a global public computer network that provides access to a number of communication services, including (the World Wide Web, transmission of email, news, entertainment content, and data files), regardless of the device used. Access is not limited to computers, but may also be through mobile phones, personal digital assistants (PDA), gaming consoles, digital television, and so on. Access may be provided through a fixed or mobile network.
- Social networks:
Social networks can be distinguished from other communication and content-related activities by the creation of profile data on certain websites.
- Email:
An electronic communication service that allows a user to send and receive digital messages to and from one or more users over a communication network. Messages are transmitted to a specific email address and stored for retrieval by the recipient, and may include text or file attachments.
- Blog:
Short for (weblog), a blog is a discussion or informational website published on the World Wide Web, consisting of discrete entries (Posts) arranged in reverse chronological order (from newest to oldest).
Data sources
Data on ICT Access and Usage Statistics for Households and Individuals are based on two sources:
First source: It is a survey of ICT access and usage for households and individuals.
The main variables published from the ICT Access and Usage Survey for Households and Individuals are:
- Percentage of households with a television set.
- Percentage of households with a mobile phone.
- Percentage of individuals aged 15–74 years who use the internet.
- Percentage of individuals aged 15–74 years who purchased goods and services online.
- Percentage of individuals aged 15–74 years who carried out government services online.
Second source: From the administrative records of ICT Access and Usage Statistics for Households and Individuals:
- National Information Center (NIC).
The main variables published from the secondary data source are:
The process of calculating the indicators is based on record linkage with data from the National Information Center, whereby individuals’ characteristics are extracted and implicitly used in deriving the indicator.
Designing the data collection tool
An electronic form (CAPI) was designed to ensure ease of use by field researchers. It was prepared and designed by specialists at the General Authority for Statistics (GASTAT), taking into account international recommendations, standards, and definitions. The questions were formulated in a specific scientific manner to standardize the way questions are asked by field researchers. The guidelines issued by the International Telecommunication Union (ITU) were used in developing the conceptual and methodological framework of the survey and identifying the core and supplementary indicators.
Questionnaire sections:
The ICT Access and Usage Survey for Households and Individuals questionnaire consists of 12 sections, as follows:
- Geographic data.
- Dwelling characteristics.
- Household access to ICT.
- Home internet services.
- Children's use of the internet.
- General characteristics of individuals within the household.
- Use of information and communication technology.
- Individual use of the internet.
- Digital content.
- Electronic services.
- Mobile voice communication services.
- Mobile internet services.
Review and correction rules:
Validation and edit rules were established in the questionnaire to ensure the consistency, accuracy, and logical integrity of the collected data. These rules were established by linking the logical relationships between responses, questions, and different variables to assist the field researcher in detecting any errors immediately when entering data.
To ensure the quality of data from the ICT Access and Usage Survey for Households and Individuals, three types of review and correction rules were established, as follows:
- Navigation rules between sections and fields:
Special rules were programmed to regulate automatic navigation between sections and fields based on the respondent’s answers, totaling (70) rules.
- Error rules:
These rules cannot be bypassed during the data entry process. The field researcher is required to correct the data by referring back to the respondent to verify its accuracy. There are more than (150) such rules.
- Warning rules:
These rules were established to verify the accuracy of the data entered by the field researcher. The field researcher may override them if their accuracy is confirmed. There are (16) such rules.
Questionnaire test (cognitive test)
A cognitive test of the survey questionnaire was conducted using a random sample of households and individuals for the interview sample. During the cognitive testing process, the following evaluation criteria were taken into consideration: (The overall concept of the question, clarity of question wording, clarity of the terms used in the question, appropriateness of response options, participants’ ability to answer the questions effectively, and the extent to which participants are willing to disclose their responses) until a report was produced providing a comprehensive summary of the cognitive test results.
Statistical population
The statistical population for the ICT Access and Usage Survey for Households and Individuals consists of all households residing in Saudi Arabia, whether Saudi or non-Saudi, as well as all Saudi and non-Saudi resident individuals aged 5 years and above, of both sexes (male and female), across the various administrative regions of Saudi Arabia.
Sample design
Sample type
The sample was designed using a two-stage stratified cluster systematic random sampling method. In the first stage, a random sample of primary sampling units (enumeration areas) was selected for each stratum of the adopted sample design. In the second stage, a systematic random sample of 20 households was selected from each selected primary sampling unit.
Stratification:
To increase the efficiency of the sample and enhance its representation of the target population, the primary sampling units in the sample frame were classified into homogeneous strata as follows: To obtain more accurate results than those of a simple random sample of the same size, and to ensure a sufficient number of households at publishable levels with acceptable precision, stratification was conducted as follows:
- Using administrative regions as the main domains for estimation and allocation to ensure that survey indicators can be produced at the level of each administrative region.
- Creating explicit strata by classifying primary sampling units (PSUs) according to governorate and degree of urbanization (urban/rural), such that each stratum consists of the intersection of governorate and degree of urbanization, reflecting the geographical and demographic variation within each administrative region, according to the following formula: Stratum = Governorate × Degree of urbanization (Stratum = Region × Urbanicity).
Sample allocation across strata:
Exponential allocation (with a lambda value of 0.85) was used to allocate the total sample across administrative regions. Proportional allocation was then used to allocate the administrative region samples to governorates within each administrative region. It was implemented using the number of housing units from the second stage of the census as the measure of size (MOS). The following is the proportional allocation formula:
Where:
- Represents the total sample size in the study domain or administrative region.
- Represents the sample size allocated to stratum h (governorate).
- Represents the size of stratum h in the frame.
Calculation of sample size:
The estimated sample size for each administrative region (study domain) was calculated using Equation (9) below. The estimated size for each administrative region was then allocated to the strata (governorates) within that region using Augmented Proportional Allocation. The calculated sample size for small governorates was increased to ensure that it was not less than 40 households.
Parameters and determinants used in sample size estimation:
The sample size was calculated using the following parameters and specifications:
- The design effect used at the administrative region level ranged between 2 and 5.
- The expected response rate at the national level was 80%.
- A confidence level of (1 − α) = 0.95 was used in estimating the mean.
Sample size estimation formula:
The design effect, response rate, means, and standard deviations for the “computer users” variable were calculated based on data from the previous round of the 2025 survey.
The sample size for each stratum h (study domain) was calculated as follows:
Where:
- Represents the frame size for each stratum h (study domain).
- Represents the sample size for each stratum h (study domain).
- Represents the estimated design effect for each stratum h (study domain).
: Represents the estimated response rate for each stratum h (study domain).
- Represents the allowable margin of error in estimating a percentage for each stratum h (study domain). The allowable error is calculated by multiplying the relative error by the value of the proportion to be estimated from the survey.
- Percentage of individuals who use a computer in stratum h (study domain).
- Represents the confidence level coefficient for the specified percentage in each stratum h (study domain).
The sample size amounted to 20623 households and was distributed across governorates according to levels of urbanization, ensuring a balance between urban and rural areas.
The level of precision was set at a margin of error of (±7%) at a 95% confidence level. The coverage and representation also encompassed all regions of the Kingdom, ensuring comprehensive coverage of all targeted dwellings within the scope of the study.

Statistical unit
The statistical units in the ICT Access and Usage Survey for Households and Individuals are households and individuals.
Data collection
Survey data collection:
Data on ICT Access and Usage for Households and Individuals are collected through computer-assisted personal interviewing (CAPI).
Data collection from administrative records:
In coordination with the relevant GASTAT departments responsible for implementing the survey and managing data collection, data for the ICT Access and Usage for Households and Individuals publication are obtained from the National Information Center (NIC), including data on the main characteristics of individuals.
The data are stored in GASTAT's databases after undergoing validation and review processes in accordance with approved statistical methods and recognized quality standards. The data source is consulted in the event that errors are detected or observations are identified in the data.
Data collection frequency
Data collection for ICT Access and Usage for Households and Individuals is conducted annually.
Reference area
ICT Access and Usage for Households and Individuals covers 13 administrative regions in the Kingdom of Saudi Arabia.
Reference period (time reference)
Reference period of the variables or dataset is as follows:
- Household identification data, dwelling characteristics, and general characteristics of individuals within the household, such as educational status, are referenced to the date of the household visit.
- Employment status data are referenced to the seven days preceding the household visit.
- Data on ICT access and usage for households and individuals are referenced to the three months preceding the household visit.
Base period
Not applicable, as the survey does not rely on calculating relative changes compared to a base year. Rather, it aims to measure the characteristics and uses of ICT among households and individuals during a specific reference period. Accordingly, the concept of a base period does not apply to this survey.
Measurement unit
The unit used in ICT Access and Usage for Households and Individuals is percentage.
Time coverage
Data are available from 2017 until 2026.
Publication frequency
The results of ICT Access and Usage Statistics for Households and Individuals are published on an annual basis in accordance with the approved statistical plan.
Statistical processing
Error detection
Data are reviewed and matched to ensure their accuracy and precision in a way that suits their nature with the aim of giving the presented statistics quality and accuracy.
An example of this is the use of the interquartile range (IQR) methodology, which is widely applied and practiced globally to identify outliers.
The calculation is done:
- First quartile (Q1 / 25%): The average of the lower half of the dataset.
- Third quartile (Q3 / 75%): The average of the upper half of the dataset.
The interquartile range measures the spread of the middle 50% of the data, highlighting values that differ significantly from the central tendency of the dataset.
The boundaries for outliers are determined as follows:
- Lower Bound: First quartile - 1.5 * Interquartile range (IQR).
- Upper Bound: Third quartile + 1.5 * Interquartile range (IQR).
Variables are identified as outliers if:
- The variable is below the minimum threshold.
- The variable is above the maximum threshold.
Following the identification of outliers, the Digital Economy Statistics team analyzes and evaluates outliers in the averages by comparing the mean and median for specific characteristics of the dataset using appropriate statistical measures. In addition to processing and tabulating the data to verify their accuracy, all outputs are stored and uploaded to the database after being calculated by the General Authority for Statistics (GASTAT), to be reviewed and processed by specialists in the Digital Economy Statistics Department using modern technologies and software designed for this purpose.
Data integration and matching from multiple sources
Data extracted from administrative sources are integrated with data obtained from the survey to derive the final indicators. Administrative data sources are directly used to feed the indicators related to the ICT Access and Usage Survey for Households and Individuals, thereby ensuring the accuracy and comprehensiveness of the results.
Imputation and calibration
Imputation and calibration procedures were implemented as part of the statistical processing phase in accordance with the GSBPM. To improve data quality and reduce bias resulting from partial or complete non-response, the imputation process included applying specific methodologies to compensate for missing values. Regarding calibration, the design weights of responding units were adjusted to align with known population totals or distributions, thereby improving sample representation and ensuring the consistency of estimates.
These processes took into account statistical quality standards such as impartiality, consistency, and comparability. All processing steps were documented for transparency, reproducibility, and verification.
The sample weights were calculated by calculating the design weight, which reflects the probability of selecting a sampling unit in the sample, such that the weight of the selected unit in the sample (i.e., the individual) is as follows:
Where:
: Denotes the probability of selecting individual i from stratum h.
Non-response weight adjustment:
The weight was adjusted to compensate for non-response or missing data to ensure sample representation. This adjustment is made after data collection and identification of response cases, according to the following formula:
Where:
: The weight adjusted for non-response in stratum (or adjustment class) h, where the adjustment factor for each stratum (or adjustment class) is calculated as follows:
Where:
R: R denotes response cases, and NR denotes non-response cases.
Method of calculating the indicators:
The ICT Access and Usage Survey for Households and Individuals aims to measure a number of national and international indicators related to ICT access and usage among households and individuals in Saudi Arabia, at both the household and individual levels. The internationally adopted formulas were used to calculate the main indicators of the ICT Access and Usage Survey for Households and Individuals, as follows:
Percentage of households by availability of information and communication technology at the administrative region level =
(Number of households with information and communication technology in the administrative region / Total number of households in the survey sample for each administrative region) × 100
Percentage of individuals aged 15–74 years who use information and communication technology by administrative region = (Number of individuals aged 15–74 years who use information and communication technology in the administrative region / Total number of individuals aged 15–74 years in the survey sample for each administrative region) × 100
Percentage of individuals aged 15–74 years who use information and communication technology by sex and nationality = (Number of individuals aged 15–74 years by sex and nationality who use information and communication technology / Total number of individuals aged 15–74 years by sex and nationality in the survey sample) × 100
Percentage of individuals aged 15–74 years who use information and communication technology by age group = (Number of individuals aged 15–74 years by age group who use information and communication technology / Total number of individuals aged 15–74 years in the survey sample for each age group) × 100
