This table lists the counties as of 2011, according to source [6]. I had to make a few assumptions to derive it. Source [6] has a column labeled "Constituency." The entries in that column look like "(Name) County," "(Name) Municipality," and occasionally "(Name) County East," "(Name) County North," "(Name) Municipality West," etc. I've assumed that in those cases there are several constituencies in a county-level division, and the name of the division is just (Name). On the other hand, there are some instances of "(Name) East County" and the like. In those cases, I took "(Name) East" to be the full county name. I also assumed that (Name) East county was split from (Name) county, wherever that is possible.

Thirty-two new districts were created in 2009 and 2010. I was always able to determine which old district each new district was split from. In most cases I was also able to determine which county was taken from the old district to form the new district. When there's only one county missing from the old district and the new district has two counties, one with the same name as the missing county, I assumed that the missing county was split to create the two counties in the new district.

In seven cases, I wasn't able to tell which old county a new county or municipality was split from. In those cases, it's possible that I failed to change a HASC code for a county whose territory has changed, which is my usual policy. Also, in those cases, the Ex-HASC column is just a guess. These seven cases are listed at the end of the Change history section.

Change history:

The list of counties here is my best reconstruction of the situation as of 2000年01月01日. I gathered information from a variety of sources, including [1]-[4] listed below. Unfortunately, as so often happens, the sources disagree with each other, without offering any explanation.

1. If this reconstruction is correct, the following changes occurred between 2000年01月01日 and 2002年09月13日.
2. The districts changed as described on the Districts of Uganda page. Specifically, Kaberamaido split from Soroti (SOchanged toSR+KD); Kamwenge and Kyenjojo split from Kabarole (KBchanged toBR+KE+KJ); Kanungu split from Rukungiri (RUchanged toRK+UU); Kayunga split from Mukono (MKchanged toMN+KY); Mayuge split from Iganga (IGchanged toIA+MG); Nakapiripirit split from Moroto (MOchanged toMT+NP); Pader split from Kitgum (KTchanged toTG+PD); Sironko split from Mbale (MLchanged toMB+SI); Wakiso split from Mpigi (MPchanged toMI+WA); and Yumbe split from Arua (ARchanged toAA+YU).
3. In Adjumani district, the five counties (Adropi, Ciforo, Dzaipi, Ofua, and Pekelle) merged into one (East Moyo).
4. In Arua district, Vurra county was created.
5. In Kapchorwa district, Bukedea, Kumi, and Ngora counties were replaced by Kongasis, Kween, and Tingey counties.
6. In Kibale district, Buyanja county disappeared. Possibly it was just an alternate name for Buyaga, and never a separate county.
7. In Kisoro district, Kisoro county merged with Bufumbira.
8. In Nakapiripirit district, the name of Upe county was changed to Pokot.
9. In Masindi district, Buliisa and Buruli counties disappeared. (Buliisa is now the name of a sub-county of Bujenje county.)
10. In Sembabule district, Lwemiyaga county split from Mawogola.
11. In Tororo district, Tororo county split from Tororo municipality.
12. The following table lists the counties as of the census date, 2002年09月13日 (Source [5]). Note, however, that many new districts were created in 2005, 2006, and 2007. After that, I found it convenient to change the HASC codes to reflect the new division into districts. That's why the table has two columns of HASC codes: each county can be linked to the district that contained it in 2002 (Ex-HASC) and 2008 (HASC).

1. Between 2002年09月13日 and 2011年01月01日, more districts split, as described on the Districts of Uganda page. Specifically, Nwoya split from Amuru (KQchanged toNW+AY); Kole split from Apac (ACchanged toQL+AQ); Namayingo split from Bugiri (BGchanged toNY+BI); Ntoroko split from Bundibugyo (BNchanged toNO+BX); Buhweju, Mitoma, Rubirizi, and Sheema split from Bushenyi (BSchanged toBH+MM+RZ+SH+BC); Luuka split from Iganga (INchanged toLK+IC); Buyende split from Kamuli (KXchanged toBY+QU); Kween split from Kapchorwa (KPchanged toQW+QP); Kyankwanzi split from Kiboga (KGchanged toQZ+QO); Lamwo split from Kitgum (TGchanged toLM+QT); Ngora split from Kumi (KVchanged toNR+QM); Kyegegwa split from Kyenjojo (KJchanged toQG+QJ); Alebtong and Otuke split from Lira (LAchanged toAL+OT+LL); Bukomansimbi, Kalungu, and Lwengo split from Masaka (MAchanged toBM+QA+LE+MQ); Kiryandongo split from Masindi (MCchanged toQD+MZ); Napak split from Moroto (MTchanged toNQ+MX); Butambala and Gomba split from Mpigi (MIchanged toBT+GM+MJ); Buikwe and Buvuma split from Mukono (MNchanged toBZ+BV+MV); Amudat split from Nakapiripirit (NPchanged toAZ+NI); Zombo split from Nebbi (NEchanged toZO+NB); Agago split from Pader (PDchanged toAG+PR); Kibuku split from Pallisa (PLchanged toQB+PS); Bulambuli split from Sironko (SIchanged toBB+SK); and Serere split from Soroti (SRchanged toSX+ST).
2. During the same period, the number of county-level divisions increased from 160 to 191, so there must have been 31 new counties created. In the main table, the Ex-HASC column will usually identify which old counties were split to form the new counties. However, there were some cases where I couldn't determine how the new counties were formed. The following table lists these cases of uncertainty.
