In my observation there's a general preference towards sedans more than hatches around here. For what it's worth, the general perception is that sedans are more practical and professional (read: fleet car/appliance), while hatchbacks are more youthful and sporty (read: lifestyle car/fashion accessory).
Some cars around here are sold in both hatchback and sedan versions: the Toyota Vios and Yaris, Honda City and Jazz, Ford Fiesta, Mazda 2, and soon, the Mirage and the Attrage. The sedan will usually have a stripped down version meant for fleet sales, and the entry hatchbacks will usually have more toys and maybe only available with a certain engine or transmission (e.g. the Toyota Yaris is only available with a 1.5L 4-banger, the Vios has it as an option instead with the base model having a 1.3L engine). Thus, the local market usually has sedans priced cheaper than hatchbacks.
However, if a hatchback was sold cheaply enough they'll sell like hotcakes. Evidence of that is the streets recently having been filled with Mirages, Hyundai i10s and Eons, Kia Picantos, and Suzuki Celerios (Alto in other markets). In the early 90's, the Daihatsu Charade, Kia Pride (Ford Festiva) hatch, and the Honda Civic hatch also sold very well. After that the hatchbacks disappeared from the market or became rather unreasonably priced; the return of cheap and cheerful hatchbacks shows that the manufacturers are willing to think out of the (3-)box in this market and they've been rewarded by quite a lot of sales.
Personally, I prefer hatchbacks. They're way easier to park, usually have more rear headroom, and very versatile. I grew up as a kid seeing my dad carry everything including a literal kitchen sink in the back of our Daihatsu Charade, so I know how very useful they can be.
Overall, market conditions notwithstanding, the Filipino car buyer's preference between hatchbacks and sedans is probably an even split, maybe leaning slightly towards the sedan side of the scale.
Slightly off topic: Having said that, most car buyers prefer neither and would go for the so-called "Asian utility vehicle" category instead. These are cars which are the result of manufacturers raiding their parts bins and are designed with "let's put together the most useful car we can sell for cheap" in mind. So, ladder-frame chassis, previous-generation rear-wheel-drive powertrains, 7-10 seats. Cheap to buy and very versatile, though not very refined. They're not the most economical, but parts are very cheap and they're very tough, resulting in low maintenance costs. I have one actually: a 2002 Toyota Revo.
