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

Text: the data is subject to twitter terms and conditions which prevent us from redistributing any data collected from the 1% api beyond the research team. however, we are able to supply two limited datasets as supporting information files: for age: user id and derived age in years. for occupation: user id, derived occupation, soc2010 code and ns-sec group. whilst we cannot provide the text from which we have derived our proxy demographics, according to the t&cs of twitter we are able to supply user ids so that others can retrieve the same data as us from the twitter api.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
