Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: the authors confirm that, for approved reasons, some access restrictions apply to the data underlying the findings. part of our data originates from statistics denmark's micro data. because statistics denmark holds detailed information on all danish citizens, public data access to micro data is not possible due to privacy concerns. for the full set of rules, see http://www.dst.dk/ext/645846915/0/forskning/access-to-micro-data-at-statistics-denmark_2014pdf. thus, we cannot make all of our data directly available in a public repository. however, readers who wish to access the data can gain access through the rockwool foundation research unit (rfru) (peter fallesen's home institution) by signing the existing data agreement between rfru and statistics denmark. remote data access is then possible through rfru's secure server as long as the individual abides by statistics denmark's rules for data access. aggregate level data (such as the number of children living in denmark in each age group, each year, and across ethnicity and gender, as well as children in foster care per december 31 each year) can be accessed publicly through statistics denmark's statbank (http://www.statbank.dk/statbank5a/default.asp?w=1920). in addition, the aggregate data used to generate the synthetic cohort estimates are available as supporting information.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
