## Appendix A The Global COVID-19 Survey of National Statistical Offices  
Official survey operations have impacted 40% of all countries that responded. However, results show that statistical agencies are adapting their survey operations by using alternative data collection methods: 58% of countries are relying on phone surveys; 53%, on administrative data; and 34% on web surveys. In most cases, all three alternative sources are used across income levels. In general, administrative data production is less affected. Here, 56% of offices reported moderate or severe impediments (mostly high-income countries). In general, two-thirds of NSOs are impacted to produce essential statistics and to meet international reporting requirements. However, low-income countries are more impacted. All low-income countries responding to the survey confirmed that COVID-19 affected international reporting requirements. While 48% of high-income countries reported that COVID-19 did not impact international reporting. Furthermore, it is not only the production of statistical information that is being currently challenged: geo-spatial information is also heavily impacted by the pandemic. The National Institute of Statistics and Geography (INEGI) of Mexico did a survey on the actions implemented by both NSOs and national geographic institutes (NPIs) due to COVID-19; some regional or global organisms relevant to these activities were also included in the surveys. Regarding the NPIs, 24 countries answered the survey (Argentina, Bolivia, Brazil, Canada, Chile, Colombia, Costa Rica, Ecuador, El Salvador, Spain, Finland, France, Guatem, Honduras, Indonesia, Italy, Norway, Panama, Paraguay, Peru, Dominican Republic's Military Cartographic Institute, United Kingdom, Uruguay and Venezuela)along with the Pan American Institute for Geography and History (PAIGH). Other 9 did not publish the information (Germany, Cuba, Denmark, Japan, Nicaragua, the Dominican Republic's National Geographic Institute Jose Joaquin Hungary Morell, Russia, Sweden and USA). From the 25 institutions that answered, 12 (Bolivia, Colombia, El Salvador, Finland, Guatem, Honduras, Panama, Paraguay, Dominican Republic's Military Cartographic Institute, United Kingdom, Uruguay and Venezuela) mention having taken measures of confinement and adopting a home office modality; 11 (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Spain, Finland, France, Italy and United Kingdom) mention having changed the face-to-face modality to digital (through servers and internet sites) in customer service, consultation and purchase of products and services and procedures; 5 (Argentina, Colombia, Ecuador, Italy and Peru) mention having suspended events, training courses and cultural activities (planetary museums); and 3 (Ecuador, Peru and PAIGH) mentioned having suspended meetings and work trips. None of the informants reported information on conducting surveys or fieldwork. Regarding the statistical institutions, 32 NSOs answered the survey (Argentina, Germany, Australia, Austria, Belgium, Brazil, Canada, Korea, Colombia, Costa Rica, Denmark, Ecuador, Spain, 2 from the USA, Estonia, France, Finland, India, Ireland, Italy, Japan, Luxembourg, Norway Netherlands, Paraguay, Peru, Poland, Dominican Republic, Sweden, Switzerland and Uruguay), along with UNECE and UNSD. Of the 34 responding institutions, 24 reported adopting remote work modality (total or partial); 8 reported having suspended fieldwork; 18 reported having suspended some of their surveys (those carried out face to face); likewise, from these 18 that reported suspension of surveys, 6 (Argentina, Australia, Korea, Denmark, Ireland and Poland) reported using administrative records to cover for the required information. On the other hand, as an alternative to face-to-face surveys, 18 entities reported having switched to the telephone or online survey modality; and 10 reported having digital services for data capture and service provision.
