st: Pooled fixed effect model

Dear Statalist members,
We have question regarding a fixed effect model to account for regional/com=
munity effects in our regression.
We would like to run the following regression:
Svy: clogit y =3D x1 x2 x3 group(v001)
V001 are the cluster units in one DHS survey.
Now we would like to pool datasets from different years for the same country. Unfortunately, the number of clusters differs between datasets and it cannot be seen which clusters are overlapping.
Let's imagine that dataset 1 has 100 clusters and dataset 2 has 200 clusters. Would it be possible to pretend to have 300 different clusters for the pooled fixed effect model? The studies may be 15 years apart, so that the characteristics of a cluster might have changed over time.
Any help would be much appreciated!
Best regards,
Lukas & Joerg
