1. Precision requirements for all data sets are expressed in standard errors and are defined as continuous functions of the actual estimates and of the size of the statistical population in a country or in a NUTS 2 region.

2. The estimated standard error of a particular estimate shall not be bigger than the following amount: 3. The function f(N) shall have the form of f(N)=a√N+b

4. The following values for parameters N, a and b shall be used: N a b Labour force domain: precision requirements Estimated (national) quarterly unemployment‐to‐population 15‐74 ratio Country population aged 15‐74 residing in private households, in million persons and rounded to 3 decimal digits 7800 ‐4500 Estimated (national) quarterly employment‐to‐population 15‐74 ratio Country population aged 15‐74 residing in private households, in million persons and rounded to 3 decimal digits 7800 ‐4500 Estimated quarterly unemployment‐to‐population 15‐74 ratio in each NUTS 2 region Population aged 15‐74 in the NUTS 2 region residing in private households, in million persons and rounded to 3 decimal digits See point 6 Income and living conditions domain Ratio at‐risk‐of‐poverty or social exclusion to population Number of private households in the country in millions and rounded to 3 decimal digits 900 2600 Ratio of at‐persistent‐risk‐of‐poverty over four years to population Number of private households in the country in millions and rounded to 3 decimal digits 350 1000 Ratio at‐risk‐of‐poverty or social exclusion to population in each NUTS 2 region (see point 7) Number of private households in the NUTS 2 region in millions and rounded to 3 decimal digits 600 0 Health domain Percentage of population severely limited in usual activities because of health problems (age 15 years or over) Country population aged 15 years or over residing in private households, in million persons and rounded to 3 decimal digits 1200 2800 Education and Training domain Participation rate in formal education and training (age 18‐24) Country population aged 18‐24 residing in private households, in million persons and rounded to 3 decimal digits 200 1500 Participation rate in non‐formal education and training (age 25‐69) Country population aged 25‐69 residing in private households, in million persons and rounded to 3 decimal digits 400 2000 Use of information and communication technology domain Percentage of individuals who ordered goods or services over the Internet for private use in the last year Country population aged 16‐74 residing in private households, in million persons and rounded to 3 decimal digits 400 1300 Time use domain Percentage of population aged 15 and over spending daily on average more than 10 % of time working in paid work Country population aged 15 years or over residing in private households, in million persons and rounded to 3 decimal digits 900 3500 Consumption domain Percentage of households whose expenditure on housing‐related categories including water, electricity, gas and other fuels, are more than 50 % of the total expenditure (See point 8) Number of private households in the country, in millions and rounded to 3 decimal digits 600 1600

5. Where countries obtain negative f(N) values with the parameters expressed above, they shall be exempted from the corresponding requirement.

6. For the estimated unemployment‐to‐population 15‐74 ratio in each NUTS 2 region, the function f(N) is defined as follows: 7. For the estimated ratio at‐risk‐of‐poverty or social exclusion to population in each NUTS 2 region, those requirements are not compulsory for NUTS 2 regions with less than 0,500 million inhabitants, provided that the corresponding NUTS 1 region complies with this requirement. NUTS 1 regions with less than 100 000 inhabitants are exempt from the requirement.

8. For the time use and consumption domains, the precision requirements may be reached by combining microdata concerning a maximum of three successive years of observations. For those domains precision may be estimated and assessed using relevant alternative methods.
